How to handle alt text for images over a gutter jump thread
How do others handle alt text when the image crosses the gutter and spans two pages? (ex: a picture book)
Do you list the alt text for the full visual on the first image, and nothing on the second image? Do you list alt text for each image separately, describing just that page? Is there another option here I’m not thinking of?

This is an interesting question! I have worked on some fixed-layout picture book conversions and from what I’ve seen, it is best to describe the entire image in one go, even if half of it is cut off and present in another xhtml file. The first half of the image can contain the description for the entire image. The second half of the image can be without a description in this case using the following: alt=”” role=”presentation”
Describing each half of the image separately might be disruptive to the reader, unless two different scenarios are happening in that larger image that spans two pages. It all depends on the image itself and the reading order you want to present to the reader, so it is best to use your judgment.
