Actually, after switching from Windows, I tried several image viewers and I’m still not satisfied with my current experience, so…

I think this kind of usage is perfectly fine.

I wonder why distros don’t come with built-in.

I honestly tried to use markdown feature which allows to use preview for each image (with click to full size), but nor iOS client, nor web browser didn’t seem to support this feature. All images in this post sum up to ~6mb I think.

Yes. Usually I look at my files in KDE Dolphin, and it’s GUI app, therefore opening them in another GUI app feels more natural.

Can you give a link?
