Hi Shents
I think that lack of response to your question is more a fact that so few of us at this forum has the full Adobe suite with Indesign.
Without actually owning the program, I guess that what is happening is that the Photoshop image will be shown on the monitor as a low ress image but the printed file will use the full size image. Have you tried to print it out to see if it is still low ress?
