I was wondering if it is possible to set my computer so that the pictures that I use for my desktop will scale automatically to my screen resolution (128 x 854). The smaller pictures are fine as is, but my larger pictures are way too big. I tried stretch to fit, fit, center and tile. Center is the closest to good - nothing get's pixelated. I'm starting to think I have to go into iPhoto, find all the larger pictures and make scaled down copies to use for the desktop.
