is the default image viewer with my LMDE - installed on my AAO netbook.
With my Debian Sid on my main PC, I use Viewnoir - works well for my needs.
There are a number of image-viewers
made for Linux.
The 'right one' depends on what you want and expect from the Application? Linux and Open Source are all about 'choices'
I would cruise through the Synaptic Package Manager to see what the preferred selection of 'image viewers' is in the repositories first.
Most of the good/popular Apps are in the repros already. Before I went and downloaded a 3rd party App. - just to get the latest cutting-edge version number of the App.
The Apps. in the repros have been tried and tested, by people who know these things. A newer version or decimal point number of a higher version - you never know what your getting.
I always wait for the newer version of an App to make it into the Debian repositories first. Then, I know it'll work.
