Another plea for help - "open with"

[david]

Ubuntu 20.04 with Unity desktop
Gimp 2.10.38 (PandaJim with Python 2.7)

Since yesterday I have lost the "Open with GNU Image Manipulation Program" for jpg, png and gif files when I am in the files menu. (tif files open normally.)
However, if I click on a thumbnail for these file types on the Unity desktop I get the option to open with Gimp.

In the gimp.desktop file there are: image/jpeg; image/png; and image/gif;

In ~/.config/mimeapps.list I can see image/jpg=gimp.desktop; image/png=gimp.desktop; and image/gif=gimp.desktop;

In addition there are numerous entries of the form: image/jpeg=GIMP-2.10.21.desktop which I suspect are obsolete as there is no GIMP-2.10.21.desktop file, only a
gimp.desktop

The only changes I have made are to fit a second monitor and to install XnView MP.

I have spent many hours searching the internet without finding a clue as to what may be the problem!

Any help most gratefully received!

David.

No need to do this the hard way, Unity must have some kind of "file associations" dialog.

Otherwise the spec is here: https://specifications.freedesktop.org/m.../file.html

Problem solved.

Ofnuts,

Thanks for the reply.
Solved by pointing "open with" at the Gimp binary - it fixed the problem for all three file types.
