I wouldn't. You're relying on the browser to supply a proper MIMe 
type, which IMHO is not the best place to put the burden.

Personally, I use Image::Size::imgsize() (see CPAN) for this. It 
automagically figures out the image's type (and size) based upon the 
file header. It doesn't even rely upon the .jpg or .gif ending, which 
would also be a bad idea.
