Not sure if this is a general issue or just the way things work - when I plug the Tour to my desktop and transfer images via Picassa (from the SD) Picassa does not allow me the option to keep the images on the card - it automatically wipes the images.
Any other card or device I've used worked as designed. Is this a limit of how mass storage works with BBs?

Have you tried just sticking your card into your computer by default. I mean all I do to put pictures, music or copy them off my card and put them on the computer is put my MicroSD into an SD adapter and put it in the memory card reader slot. I just cut and paste everything into the various folders or I copy and move them out so I can have them on my desktop.
