I have voted for 7 per week but I really think it should be 3-4 per week and not more than 1 per day. Being selective is one of the most important qualities for an artist and this will teach us to be more selective, and force those who upload just to see their name up there no matter what, to exercise a little very good self-criticism. I also think that the WIP gallery should be free (no limits) but should also be deselectable, i.e. one should be able to choose to see "all galleries except WIP"
