Need help with either clipart for my game or how to add my own to it

I finished making a game similar to Rainbow Six Siege, and have made my own art but it won’t let me add it in the publish section, so either clip art or any ideas on how to add it would be greatly appreciated, thanks

Hi @Nill ! What device do you use? If it’s a google device (like chromebook) (maybe I can only use a Chromebook) I can help you fix it. The problem is it’s too big for the slot, right?

Is it a JPG file?
If not, that may be the problem

yea normally for me if it wont let me use it I just make it jpg and it works but that may not be the case just a possibility
