(Nondescript image.) View north east from > twenty three high street. I fear it would often *not* be that good without an explicit association. The automated reader wouldn't know how the paragraph was related to the photo, except that they're on the same part of the page. It would often say "321098412.jpeg" as part of its own fallback. An explicit statement (such as aria-describedby) would tell it that the author did consider this a caption/description/something, and that the reader doesn't need to go through its fallback routine. -jJ
