When I tried to use this with osiva , it didn't prompt me to make it click-through like it did with framed/rectangular-bordered programs. So I searched online and found opti, which seems like basically the same thing but with a rectangular border. But I can't for the life of me figure out how to import images of my choosing into the program, could anyone help? Source: almost 2 years ago
I use Pix that comes stock with Linux Mint. It has a couple of different viewing modes, the one I think you want is file tree on the left and thumbnails on the main screen, you can drag and drop into folders. If you double click an image it goes to thumbnails on the left with the main part being the image. Source: about 1 year ago
