Ever want to post art for a DTA but are worried that it's going to be stolen? Here's a very simple way to watermark your projects that CANNOT BE UNDONE. First, upload your art (preferably as a sprite.) Turn it to vector mode and write the word "watermark" (or draw a line). Then group it, turn it to bitmap and turn it back to vector. Your watermark is now incorporated into your art and not moveable if you move the sprite. Happy coding!
