Perhaps a PDF form...?
The problem with doing it so you update the ID file is the person doing it needs to have ID and some knowledge, not typically true of the average office worker.
Well, that would be a reasonable output, but this person has to actually input all the content first. Like I said, it's a photo with small amount of associated copy, and (new info) it's set up in two columns currently.
Sounds like a real good candidate for InCopy.
You really should look at the capability of a PDF form, too.
This might be overkill in this particular situation, but this is exactly the type of scenario for which many will use InDesign server, front-ended with a web client to merge designated content into a template and ultimately yield a PDF file for either display, print, or both!
The problem of a “typical office worker” using InDesign is that it has a very steep learning curve and there is so much that can go wrong (not that this can't and doesn't happen with Microsoft Publisher or Word as well)!
One other possibililty would be either a script and/or custom plug-in for InDesign to perform the daily fill-in and/or replacement with minimal user interaction.
