I recall the last time I did this it didn't seem as easy as I thought it would. My android phone connected to the PC via USB cable and the PC recognised it but could not look at the files on the phone via explorer. If you pull down the top menu is there an option to set it to admin mode? If there is and you say okay you can then see the photos on the phone in Explorer on the PC and copy them over. Sorry I can't find a link to a guide, I have to dash off somewhere now!, but hope that helps.
