I didn't think of a floppy

(most of what I backup / recover would be in gigs).
A floppy will work fine as long as none of you jpg's are bigger than 1.4MB. In that scenerio, just choose the individual files a few at a time until PC Inspector tells you that there isn't any spave left, then start with another floppy. Hopefully you don't have too many jpg's to backup (might be alot of floppies).
I'n not sure on the USB to USB networking (never tried it). What is the model number of your Dell? If they have firewire ports, you can network that way.
