Images play an important role in web publishing, and WordPress makes it easy to add images to your content in several different ways. What you probably didn’t know is that taking a few extra minutes to fill in the “Attachment Details” for your images can improve their communicative value, create better user experiences for your visitors, and bring more people to your site.In this article I’ll explain what the Title, Caption, Alt Text, and Description fields are all about and why they matter more than you think. Every Image has its own Attachment Post The Attachment Details fields show up any time you add an image to a post or pageLet’s start at the beginning: When you add an image to WordPress, whether it be as a Featured Image (previously “post thumbnail”), an image in a post or page, or as a header image, you are actually creating a new Attachment Post. Once the image is added you can edit its Attachment Post by clicking the Media button in WordPress admin. This gives you a list of all the attachment posts associated with uploaded media items on the site.Depending on your current theme you may also be able to access the Attachment Post page for the image from the front end of your site, and this attachment page may display some of or all of the meta data associated with the image. Images and Attachment Posts can carry a lot of metadataWhen you add a new image to a post you are prompted to add so-called “Attachment Details”. These attachment details are probably the most ignored and underutilized features of WordPress and if you learn what they are and how to use them you’ll never ignore them again: TitleThe title is the only attachment detail required by WordPress. Title defaults to the name of the file but should be changed to a descriptive title of the image. This is the title of the Attachment Post for the image and just like a regular post the title will define the pretty permalink for the attachment post.
You can also use the Title to search for images in your media archive.In previous incarnations of WordPress the Title field was mapped to the optional HTML. This resulted in the title of the image appearing as a tooltip any time a mouse hovered over it. In the current incarnation of WordPress the title attribute for the image itself and also the optional image link are added separately.
To do so you have to add the image to the post, then reopen it by selecting it and clicking the pen icon in the top left hand corner, and toggle the Advanced Options section of the Image Details modal window. Here you find Image Title Attribute as well as Image CSS Class , Open link in a new tab, Link rel, and Link CSS Class. The Advanced Options under Image Details allow you to add title attributes to your images. CaptionThe caption is the text traditionally displayed underneath the image though the exact placement will vary depending on your theme. The caption is not tied to the attachment post but to where you choose to place the image in a post.
That means if you use the same image in several different posts or several different places within a post you can have individual captions for each.In WordPress captions are added using the shortcode which wraps around the and optional tags. This is why you can’t move images with captions in the visual editor but have to do it from the code end.
For the image above the entire embed code complete with caption shortcode looks like this:caption id='attachment2896' align='aligncenter' width='700'The Advanced Options under Image Details allow you to add title attributes to your images./captionIt is worth noting that WordPress image captions can contain HTML including links. Alt TextThe or “Alt text” is mandatory for images on the web but is often ignored because it seems unnecessary. This is unfortunate because the alt attribute is both important and powerful.The alt attribute is the text that displays when an image does not display. Hey Morten Rand-Hendriksen,Great article!i am currently searching for a wordpress plugin or even a cms that would allowuser to input meta data into a jpeg file for example in an image galery, under each picture, there would be some fields where the user can input the values, like:model namephotographerect.and those infos would be written in the meta data section of the jpeg file i was wondering if its a feature that is used alot?
Maybe it has a name? Have you ever heard of a plugin that allows that in wordpress?thankyou very muchVito. Hi MortonI was talking with Joe Dolson about the use of alt tags with images and how if we duplicate the caption in the alt tag then we are actually creating redundant content for the screen readers. He suggests we use the tag instead of duplicating the content as you have suggested above?For example if I had a picture of Bear eating fish in stream alt tag would be Photo of bear eating fish in stream Which is actually the duplicated of the caption.I though of it this way.
If you have someone reading you a book would you want them to repeat every sentence?So in your post it saysIf the image has communicative content (either says something or is illustrating something that has relevance to the content on the page) the alt text should describe the content either by repeating the text in the image or describing its content.Aren’t you saying duplicate the content? Also if they content is already in the caption why aren’t you suggesting people use the aria-describedby attribute?. The breakdown I provided in the article is the official alt decision tree as mandated by web standards.
The scenario you are outlining is an addendum that has to be considered separately. The alt tag is not just about accessibility but also situations in which the image fails to load or is indexed in other ways. While duplicating the content may be annoying for a non-sighted user, excluding the alt tag may go against standards. There may be a way of making this conditional so images with alt tags hide the captions for text-to-speech browsers or similar. I am not sure.Bottom line this is more complicated than simply a matter of duplicating content.
There are two conflicting standards at play. And captions are not mandatory. In most cases they are not used. So as you say it’s not wrong their are just two different standards at play.As Monzilla suggests that:Note: Opinons may differ on how assistive technology should handle this technique. The information provided above is one of those opinions and therefore not normative.Which was my entire point on WP Bacon. This post differs then what other accessibility developers have suggested and talked about.Also as a side note about accessibility I noticed that my link in the comments didn’t have a underline or a hover state when you click on it.
Both of these opinions are valid in different ways; image alternatives are, to be blunt, much more complicated than they may seem at first glance. It’s important to consider whether the image has a caption; whether that caption conveys the same image as the alt attribute would (since sometimes a caption only conveys information about the image, as opposed to representing the image).Every alt attribute context needs to be considered uniquely. As a software developer, where I’m not specifically providing the content, I generally lean on the side of providing more content, although avoiding duplicative content is still desirable.The bottom line tip to always provide alt attribute text unless “purely decorative” is fair; but has to be considered as a very simplified version of what would be an ideal decision process – but any decision making process needs to be based on an actual scenario with actual content. If I was making a general recommendation of best practices, this bottom line tip is exactly what I’d go for. Special cases are always going to be present, however. Interestingly I ran across your post when trying to solve the problem of displaying descriptions with an image, either in a post or attachment.
You seem to indicate that the description is supposed to automatically display with the attachment post, but it does not in twenty thirteen. I’m still seeking a resolution to this, but it would be fantastic if it did display. From my recent experience with twenty thirteen it appears to only automatically display along with images in the carousel. That being said, I really appreciate the clarification on the alt id field as I’ve pretty much discounted it. I will be reevaluating how I use that field now. Hi Morten and thanks for an informative post. I have the same problem as Esther (posted a year ago) and I’m afraid in your answer you are missing the point.
I am currently using the “FooBox Free Image Lightbox” and “Foogallery” plugins which work nicely together.The problem is that the images descriptions are correctly displayed under the images when I click on the thumbnail in a gallery, but NOT on images inserted individually if I use the Add Media button in posts or pages.This is not a Themes issue. The problem is that on the Insert Media modal window you can see (and edit) all of an images’ properties (Title, Alt text, Caption and Description) but after you’ve clicked the Insert into page button and are back on the Post (or Page) edit page, the only attributes of an image media that get inserted are src and alt, and the Caption attribute is inserted in the caption tag.Upon examining the text source of a Foogallery gallery, I can see that it inserts this bit of code in the attachment’s. Hi Morten,I’ve been racking my brain on this onemaybe you could help?I think this goes along with duplicate phrases/keywords that are being asked in these comments.If I have images used for tutorial type stuff, e.g. Bang the hammer on the nail.Now, I’d like to put in the image description in wordpress the text “bang the hammer on the nail”.But, I also use that text below the image in my wordpress post. (bang the hammer on the nail”)Would there be a problem with duplicate phrases in the image desciption field and the same post text ruining my seo?Using caption instead of post text would be the easiest answer but, I can’t use the caption, I need the text to be in my post for schema.org reasons.andThis is not refering to alt text.that would probably be something like “A hammer hitting a nail into a piece of pine wood.”Anyways, I’d love to hear what you think or if you need any info just let me know. Thanks for your post. Image metadata is so under used across all applications and your doing a good service here.anton.
Alt Caption Instagram
Hello, thank you for such informative article:). The guy who helped me to “build” the blog or doesn’t know anything or was too lazy to explain me – like he told, I don’t need to fill any lines near image:(.
So all my posts build in wrong way. I just wrote new post, with all recommendation from Your article. Could you please look at it and tell if I understood everything correctly – maybe made some mistakes? After it, I will try to update all written posts, to make my blog google friendly:)Thank You:). Great article, super informative. I’m wondering if you can clear a few things up for me. Once I realized the importance of filling in the fields for Caption, Alt Text, Description, etc, I went back into my media library in wordpress and meticulously filled them in.
However, when I went back to my posts to see my new captions, none of them were transferred.Also, do you have any tips for how to make the sections different? For example, if I have a photo of a plate of shoestring fries, my caption might be “Shoestring fries from The Spotted Pig, NYC.” Is it ok to use the same thing for alt text? I’ve read that it isn’t, but I’m not sure how much more creative one can get.
Would I include the name of my blog in the alt text for google searches?Thank you for your time.Rebecca.
