this does not happen when i remove the memory card
any idea of what icould do to solve the problem?

Sounds like something has got corrupted.

This is usually caused by problems with the memory card. Try taking the card out and see if you still get the problem. If you dont it si the memory card. You can try reformatting the card, but it mayeb that you have to get a new one.

If this doesn't work... Short of doing a phone reset I think you would might try deleting things from the gallery (you might want to do this via PC Suite because then you can copy them away first if you want to keep them).
