Try a poison null byte attack (http://archives.neohapsis.com/archives/snort/2000-11/0248.html).

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
