Hello, I don't have an official limit, but I generally don't like to see the galleries flooded with one artist's work. It's for that reason that I kinda curate and move things around, to give artist's who submitted work years ago the front page occasionally. So, feel free to submit what you want, just know that some of it may not show up on the first pages. Or maybe it will for a while, then get moved later...ya never know
