Ok, So I am an avid Camera user, and share pics all the time. I have a 2 gb mem card, and usually can access my pics that are saved on it easily through the media-pictures-media card link. doing that does bring up some pics, but not all that I have. there is 1.7 mb left of space, and the pics are not in my device memory.. where did they go?
Try this, when you open up your media app, before you select pictures press the menu key, select explore, media card, blackberry, pictures. Hopefully you'll find them there. Or you can hook your berry up to your computer and explore the SD card from My Computer, it's usually the G drive.
