Is there any way to shrink the file size of these photos? I just want it to look look good on the ipod touch screen... I don't need the ability to zoom in or display them on a tv. Most of the files in my "ipod photo cache" folder are 800kb - 1mb. If I could get that down to 100kb or so per picture, I could save a lot of room. Any ideas? I really don't want to resize a bunch of pictures 1 by 1.
