I have an ipod nano and there are pictures on it that take up a lot of space that i dont want on there, i have tried everything i can think of to delete them but i dont know how to do it, if anyone knows how that would be greatly appreciated !

1) Plug in the Nano to your computer
2) Open iTunes
3) Click your Nano
4) Go the the Photos tab
4) Uncheck the box which tells the Nano to sync photos

well is it on a mac or pc?
because i have my ipod & itunes on a pc not a mac so yea
but on the pc. go into your pics and look for the folder called IPOD photo cache and delete the pics you dont want
