Gallery problem and brush behaviour

Hi I cannot seem to get a image upload to my gallery to remain, every time I go back its gone?

Something I;ve noticed with brushes is that when I try to just do a dot it puts paint down at the full size of the brush rather than obeying pressure, if I use any movement its fine and will make small marks according to pressure of the pen but for dabs or dots I get a big splodge.

Sorry this should be in the Rebelle forum, I cannot seem to delete it, Gallery issue has been resolved.
