Absolutely Not! Gimme a little credit here people, I'm better than that :) Every thumb and full size item resizes itself in flash to be as large as it can go within the design constraints, unless they are smaller than that, in which case I leave them, we don't want stretched stuff! The thumbs go off of whatever size you make the movie clip for them in flash (this is covered in the help) and the full view go off of two variables (also covered in the help files).
