Anchor link for long descriptions of complex images
Complex images and text alternatives
If you include a complex image you will need to add a long description. w3.org Image Concepts explains different types of images and how to add the appropriate text alternatives.
To describe a complex image you can:
- explain the contents of the image in the surrounding text.
- add an anchor link to a long description.
Anchor link
If you would prefer the long description to be at the end of the chapter, you can create an anchor link from the image caption to the long description. It would require these steps:
- Still add short alt text to the image e.g. Insert the title of the image. Image description available.
- Add a heading at end of the chapter – Image descriptions
- Add the full description under the heading e.g. Figure 1.1 Image description: Insert the title of the image. [Add all the text and detail of the image].
- Just before that line of text add an anchor e.g. fig1.1 Note: it is case sensitive and is best to not have any spaces
- Back up in your image caption add the words Image description
- Highlight that text and click Insert/edit link. Click the settings cog to select the internal link you just added.
- You could also add an anchor link back up to your images so they can go back to where they were.
