Pictures...

I sat down at my computer this morning to upload some pictures from my camera from this long weekend's festivities. When I open my camera and hook the USB cord up to my computer only 1 picture shows up.... said camera proceeds to tell me that my pictures are in internal memory. Well where is that?? I don't know where internal memory is and I don't know where my pictures from the Grasshopper game, Meagan's birthday, seeing Outformation at the Blind Tiger last night pictures are!?!?!?! DANG IT!!!!!!
