Keano, I hear you also.
I still think it would be so much quicker and easier starting with InD.
Nope.To take all these photos and export them out as tiffs and place in ID would take too long.
I shift+click all my photos in the Bridge, drag and drop right into the InD file. Then click to place (cursor is loaded) photos on their pages. (takes a nano second).
Well some have to be resized and update the link. No biggie.
InD support psd files. No need to even convert to tiffs.
I do not know. You will have the ask the person doing the printing and tell him how you created the file.Shouldn't really be noticeable don't you think?
BTW, I work on educational books with hundreds of pages.
