You need to find teh My Catalog.PSA file - in a hidden folder in Docs&Settings somewhere. You can open that with MS Access. There is an obvious table that lists all the images and [if I recall] a couple of columns that contain the filenames. You need to do a Replace on those columns to change "C:/something/image.jpg" to be "D:/somethingelse/image.jpg". Does this make sense? Obviously you should keep a copy of the file until you're done.
