Images were always linked as PSD or TIFF – flat or not, they still made the indesign file large…
Vector imagery was also linked as EPS and AI files.
The Save As did not work at the time (I did try this for other jobs using the same assets to no avail).
All artwork was for print (and for a very large client), it goes without saying all assets were resaved and flattened to 4 colour 300dpi imagery.
The only option I haven’t tried was the idml file and re-open as Indd file.
One of the retoucher lads in here where I work, reckoned that each image must have stored IT systems-related-info to do with the studios that had setup the facilities of the studios who provided me with the assets (!!) Sounds a little far fetched but I’m slightly inclined to believe it.
Seriously people. My only option that worked was taking all the layers from each PSD file and placing into a new file of the same size, and saving it as a tiff/psd etc.
The most bizarre InDesign problem I’ve encountered in my 15 years or so in the profession.
