The normal operation to move data in a computer system is via the processor but many bulk transfer devices use "direct memory access" or "DMA". The transfer process uses data buses to move data from one peripheral to another without loading the data into the processor. Not only is this a faster way to move large amounts of data it also frees the processor to carry out other tasks.
DMA is generally performed under the supervision of the processor even though the processor is not directly involved in the operation.

First, you must have a memory stick (duh), then, if you don't have one already, buy a usb cable (must be type 5 pin, the same one that works for Motorola phones), and once you access the memory stick on your computer add the pictures to the "PICTURES" folder on the root of the drive or open the "PSP" folder and add them to "PHOTO". if these folders are not already on there, add them to the psp and make sure that they are in all CAPS. Once that is done, you should be able to view your pictures on your psp. Note: even though the psp supports GIF files, when you view them under the photo option they will not be animated
