I installed gpicview (to view pictures, as the name suggests). I want it to be the default image viewer program, but it is not listed in the application list (Right click on an image-> Properties-> Open with...). I also downloaded some programs (not in the repository), and I couldn’t find out how to associate them with a file type.
As I remember it, in some older versions of Ubuntu, there was an option "Browse...", and you could choose the programs you want to use. Is it still possible to do so now?
And I think the "Open with" function looks a bit clumsy, because it lists the same program several times (for some programs installed through Wine). Anyone knows how to fix it?
(I am using Ubuntu 12.04 now)
Edit: pcmanfm works fine in this case.
