One of the things I really miss in Linux - two things, actually - are (a) a good photo editing program, comparable to Irfanview, and (b) a really easy-to-use panorama maker that doesn't require the user to do all the work. So today I'm pleased to report I've found a well-equipped photo editing program, Fotoxx. After you install it, go into your terminal, and type this command:-
sudo apt-get install libimage-exiftool-perl. That is required to make Fotoxx better able to do its thing. And then choose a main folder for it to use for its automatic searches for images. After that, you're ready to work with it. Enjoy.
