I just tried to save 7948 pictures (723 mb) to my ipod touch and had like 3 gb of space free.. But it gave me an error message like "some of your photos couldn't be transfered because there is not enough space". the capacity bar says there are 2,18 gb of photos saved on my ipod (those ~8000 are the only pictures i ever tried to transfer).. is this supposed to be like this? please explain it to me.. 4486 photos are missing, the other ones take up way too much space and there's a 5gb folder of ipod photo cache on my hard drive, i don't get it. could you please tell me WHY this is happening? or even a way to prevent this from happening? EDIT: oh, and the quality of the pictures that actually ended up on my ipod suffered quite a bit.
