Well, may I disagree a bit. If by side by side you mean only 2 in view that that is comparable, and T+ is not limited to 100% zooms. I already own T+ and used it exclusively when I owned PCs; there was no expense. I'll look at IDimage.Hi Rich - Idimager has this capability with its LightTable feature - you can get 100% zoom boxes for lots of images at once and as you move the cursor, it matches all the images... Imatch does this as well with the side-by-side compare feature.. both are much better products than T+... I highly recommend you purchase either package before T+.
