File upload - Double extensions - Why certain file formats work ?

Just that ! I tried with one image format, doing one of the techniques mentioned in the attached paper to the exercise and it didn’t work out. The server would just return the picture or in case there was no picture uploaded at all, a small white square. The code was not executed.

However, changing the file format did manage to execute code in the server.

Any idea why some files are returned as pictures by the server and in some others it parses and executes embedded code ?
