MINT 19.3 V 0.98.2: Best app to organize, batch resize, rename, move, copy pics. Very easy to get hold on, intuitive, stable.
It will install apps that index your thumbnails without any confirmation. OS was jammed and it take lot of time to resolve that problem! Do not install that before you read all documents carefully!
I used it on Windows an I can`t work without it in Linux Mint. In my opinion best app for managing the pictures. Sadly is not up-to-date and are some glitches, but after tuning works like a charm!
This is a fantastic intermediate picture viewer/editor. It's simple to use and does everything I need. It's not Gimp by a long shot, but it's much more capable than the other basic viewers. Finally I have a Linux alternative to Irfanview!
