We've never had a problem with our memory cards or hard drives going through the scanners at the airport. I would urge you to look into buying a storage device for your digital pictures rather than paying $11 a pop to transfer. I got one for about $70 off ebay, it's a hi capacity hardrive the size of a pda and holds about 4000 8mp pictures. I have heard that ipods can be used for this purpose, but not 100% sure of the logistics or truth to that!
