As rageaholic said ... google your image first -- and then mess about with it in whatever program you use!
Or if you want something other monkeys you could just make one from scratch and see what you make!!!!
Thats what I've done a lot of times ... this current set was me messing about with the Aurora brush and finding the brick texture!! I forgot it carried on doodling until I found the exact right font so I made it into a set.... Try it if you run out of ideas - you could do something cool!
Or theres the other option of just using a random image from Google and then just adding the necessaries.. border, text, subtext. With/without background.
Sometimes works....... or at least gives you a starting point!
