I've tried to follow some of the better tutorials on here on how to do this, but to no avail It shouldn't be THAT hard but all I want is the white background removed from THIS picture. I'm trying to use it as a gag on a photo is all, and it looks really cheap with the blocky white-background Sorry if this is in the wrong area, I wasn't sure where to put this. But I'd really appreciate it if someone could help me
