I can't find any definitive information pertaining to this question. I have some images I want to install onto my iPod. Now the original size of each is about 20mb, 3032x2028, .tiff format on average. What I have done (using PS) is reduced each to jpeg, reduced to around 2mb but they are still around the same dimension. I thought it a good idea to make them loose a bit of weight (aka 20mb down to 2mb). I have now made a new album in iPhoto and transferred the jpegs there ready to copy over to my iPod using iTunes. My questions are; 1. Did I need to do all that? Say I left them in their original size and format, when I copied them over to my iPod would they have been resized in any event thus reducing the dimensions and mb size or would they remain a hefty 20mb each? 2. Also having reduced them from 20mb to 2mb do I need to change the dimensions as well (3032x2028 to something smaller) or is that taken care of during transfer via iTunes?
