I have been messing around with my system and forgot to do a back up, I managed to copy some files that will help me set up the customising for next time I install Ubuntu (I format and reinstall a lot, an obsession of mine) but I don't have the permissions to copy over the Pictures folder, I don't have these pictures any where else and all I want to do is copy the pictures to another drive (im using my iPod for this) but it just wont let me. I have hundreds of photos and they have great sentimental value to me,
can anybody help me out? I'm desperate.

Thanks for any help in advance,
