I keep saving the game prizes I've won and want to put them in my signature, but they are white when I save them, and I don't want them on that white background. It's very distracting! Help me?

Your problem is that you are either saving them or uploading them as the wrong file type. They need to be saved as .png and uploaded as .png. If you are using imgur.com, they will automatically change to a .jpg and no longer work properly. I'd highly recommend photobucket, or www.postimage.org/

Thanks NQS! ^^
