(C++) Look if picture is on screen

[idelta89]

Hey there,

Is there any way that I could look if a picture is on the screen?

Example:
I want to look if this picture is on the screen http://puu.sh/7wn0G.jpg and if there is, then click it.

There's a lot of ways. It'd be easier with more specifics such as:
1-Is the picture part of a known program/window ?
2-Can the picture always be in the same position of that window ?
3-Website/local program ?
