I'm familiar with being able to have automated captions for a single image (through Meta data) however I'm wondering if it's possible to have all the images of a page included in a running paragraph of text, rather than individual blocks? I.e, so all image captions are included in a single block of text.
You may be able to trick it... 1. Create your captions on a separated non printing layer with a specific and unique paragraph style. 2. Create a Table of Content to capture that style only, and enable Run-in option.
The only way I think you could do this would be to use Table of Contents. You would still have to have each image have it's own caption like normal. But if you used a custom paragraph style, you could then generate a Table of Contents which would bring this all into one text frame.
The only other way to do this would be through scripting.
@Jean-Claude TremblaySorry i was writing my reply and didn't refresh to see somone answered or not. @supernaut_auWith the scripting method if all the images are in a folder you could easily get a python script to give you a list of names, which would be easier than looking for a script that runs in indesign. (if you are on a Mac, python is built in)
