This is a wild guess.... seriously, not being sarcastic .... If you have another microSD card, try it. Or reformat the card you have. Or, last resort, set the BlackBerry to save to main memory, just temporarily for a test, and remove the card. Then take a picture and see what happens.
Another thought is to first remove the media card, wipe the end with the contacts with a dust free cloth, then reinsert and make sure the card seats. Then take a test picture. If that doesn't do it, then try the steps in the first paragraph.
