Screen Shot Limit??

Is there a screen shot uploading limit?Say you can only upload 10 screens per day or something?Yeah I know the screens have to be approved first, but....
Just asking cause I don't want to be wasting time uploading screen shots if there not gonna show.

Only 3 screenshots per game. I uploaded like 50 screenshots once, one to each NDS game I did.

*4 screenshots per game.
