How to encrypt an image (and other stuff) graphically on linux (lemmy.zip)

Hi, I want a nice easy-to-use graphical program which can show image thumbnails atleast, and provide an easy way to encrypt images, and ideally other files too. I heard of a few programs but some dont show images and some look a bit dated ui wise. Seeing image thumbnails is pretty much a requirement as it would be alot of swapping back and forth otherwise.

I am using KDE (and nixos), I dont think that matters much for what I want.

Without using fde such as through luks. You can't be 100% sure it's not stored (at least temporarily) in unencrypted locations such as swap or another program's temporary place. That would make it trivial for someone to run data recovery software to retrieve it. Thanks to hardware accelerated encryption there shouldn't be any significant overhead. Your boot times might be marginally longer.

Having a separate encrypted space like what you're asking for is helpful if the medium is portable or you intend to give it to another person.

Also note that thumbnails of your files will be stored in a different folder on your drive. These would be generated by a file manager or file chooser dialogue.
