Malicious file upload in .JPG or GIF format

Dear List,

I'm doing Web Application Pen-Testing. In one of the pages there is an
option to upload an image(.JPG or .GIF).
How a hacker can exploit it and what are the chances of uploading a
malicious .exe file (virus kind of stuff) in .JPG or .GIF format by
changing its extension.

Thanks in advance,

Whitehat
