Use the USB cable that came with your phone. connect it to your phone and the insert the other end into your PC, then having downloaded Nokia PC Suite free from their website you are able to transfer pictures to and from your computer and phone..
OR
You can insert a bluetooth dongle on your PC and switch the bluetooth on your phone and transfer files that way..
OR
If you are using a card reader then you can move the photos that you want to your memory card and insert your memory card in the card reader and upload them from there..
OR
You can send the photos to your email address.. but I would only use this method as a last resort, the above three are the quicker and cheaper ways.
