Hi,
The following one is a merge from the one I have in Archlinux and the one in Ubuntu. It is aimed to be improved and provided upstream to the feh developers who do a nice job improving their program.

I don't know German so I could not do it the right way for the "Comment[de_DE]=" line.
There are also these lines:
StartupNotify=false
NoDisplay=true
Hidden=false
which I don't know what they are for and if they are useful : in the Archlinux version they are not written... well I guess one or all of them prevent the launcher from showing in the menus... :-(
For whom does not yet have the feh.png image, here is one:
