Plain view on image in tree in gitweb results in binary output in browser

Hi all,

Plain and head view on an image in a tree in gitweb results in binary 
output in browser. One gets numbered lines with exotic characters.

Is it suppose to be like this in gitweb would it be better to, according 
to the mime type of the file, show the actual image in the plain or head 
view?

Is this configurable or a feature request?

Regards,

Pander
