kodak camera

this thing is totally ticking me off today. I have about 30 pictures on there that I wanted to put onto the computer so I could post some of them, and so I could play with the editing instead of always going to WalMart to print them. The only ones that will show up when I try to add the pictures to the album are the ones that are on the internal memory of the camera, not the ones on the memory card. They show up as being there, but there isn't a picture, just a little X in a box. I tried to upload them anyway, and then I get told that the file wasn't there or was damaged. I can look at them in review mode on the camera, but I can't get them onto the computer. Don't know if its the camera, the memory card, or the computer, but I am getting a little frustrated!
