How can I transfer my Pictures from com...

Ok so I want to transfer pics to my camera... I don't have a slot in my laptop to put my memory card.. But can I transfer my pictures to my camera with My SD Memory Stick Adapter ? If so , how? cause I've tried to drag the pictures to the file and it doesn't show up on my camera... When I open the file there is a file named DCIM and a file named MISC.. I tried to put it in both didn't work.. Inside the DCIM there are two other files 100KC315 and 101_PANA.. Tried both of them..didnt work... what do I do? I tried with my older camera and it worked but with this camera it doesn't I just got it yesterday and I just want to do that so I can print them out and delete the ones on my camera ... THANKSS so much for your help!
