Photoshop has such a script, is there an ID?
Photoshop files can have a problem with excess ancestor metadata, which can be cleared via Javascript. Ancestor metadata can find its way into an InDesign layout, and if that is your problem the ID document’s file size would be unusually large.
You could try this script, which opens placed Photoshop files, clears ancestor metadata, updates the links, and does a save as. Make sure you have a reliable backup of the ID file and its assets before running the script.

var l = doc.links.itemByName(lnks[i])

lPaths.push(l.filePath)
