If you want to go full on addict, there are online and downloadable tools for making logos and uniforms. You don't even need a picture unless you want something exactly like a real world uniform. I have used pickoff for logos and there are online jersey and cap creators linked in the mods. I have played since OOTP 1 so I spent a good part of my graduate school years messing with stuff like this.
I probably need to do a compilation of graphics I have a ton of logos and jerseys on my hard drive. Most of it is from others though and some of it I don't really remember what year it is from.
