ok the one that is on the touch isnt horrid, but its nothing to write home about. I recently tried the pocketcm imageviewer
http://www.pocketcm.com/imageviewer.php
But it randomly stops loading images and is kinda akward at times (still not finished so understandable) But when it works i love it. Anyone know of any other picture viewing programs that are similar to the pocketcm one? like something fast and easy to use.
