.exe -> .jpg

So I have a simple keylogger that I'm trying to get onto a friend's computer, however they're all smart enough to not open any exes from me. I'm pretty sure there's a way to embed an exe inside of a jpeg where when you open the picture, you execute the program.

Would you install shit emailed to you, even if it looked like it came from a "trusted source"? Even my grandmother is smart enough not to.
