You must transfer them to your memory card before connecting the nokia 6300 to your computer via USB cable. Then select Mass Storage Device, Now on your PC/Laptop double click My computer then select the "Removable Drive" Usually it's "F:/" but it may be different for you. It should be located in the "Images" directory within the removable drive. Then just simple drag and drop.
what if the phone doesnt have a memory card?
can you still put pics on to the computer?
