I'm a computer tech for a living. Here's the easiest way to get your pics onto the usb drive:

Insert the usb drive into your pc
close any windows that pop up after inserting
go to My documents, then My Pictures
left click on any ONE folder or picture
now hold down the CTRL key and push the A key (which selects all)
now without moving the mouse anywhere, right click and select "send to 'name of usb drive' "

If your drive is a KIngston brand, it will probably appear as E:Kingston for instance.

BTW, the pictures are NOT stored in Picasa, they are where ever you saved them, which is usually in My Pictures. Picasa simply finds them and add them to it's list of photos. Some cameras will save them in a totally different spot, like /program files/Olympus.
