I've never owned an iPod and I plan on getting the iPod touch as a gift for someone. My question is: They have a fairly large collection of photos in iPhoto (maybe 6GB) and most of the images are rather large TIFF files (maybe averaging between 6 - 16 MB each). Upon syncing, is there an option to reduce file size (and maybe convert them to JPEG) so that a lot of space on the iPod touch is not consumed by image quality that won't be discernable on the relatively smaller screen size of an iPod touch. I'm asking this to see if I can get by on the 16GB model rather than the 32GB one. Thanks.
