About this time, I am a little more than intrigued and a bit confused. I use my image viewing program qimgv (github) by typing qimvg 87956_60.png and was shown a photograph of a man seemingly turning his head to look at me. Source: about 1 year ago

Qimgv - Image viewer. Fast, easy to use. Optional video support. Very powerful, qt app, best for me. Source: over 1 year ago

I use qimgv, It's mostly frameless (It only has a window bar), supports going left and right through images, even sorted by date and even on a directory with 80k+ files in it. It also has some very useful features in the right-click menu and also has a folder view and is highly customizable. Source: over 1 year ago

I don't know exactly what you mean by "nothing", but JPEG XL is already supported for almost all image viewers on Linux installing the libjxl plugin system wide, and on Windows good image viewers like XnView, IrfanView e my personal favorite qimgv, and all most used browsers already supports jpeg xl, however is not enable by default and you need to enable it in the hide settings, but I agree that you probably will...

My personal favorite is qimgv. It even supports videos with an additional download, which is awesome for me. Source: about 2 years ago

They have linked the unofficial version in their GitHub repo https://github.com/linuxmint/warpinator. Source: about 1 year ago

You can then use Syncthing or Warpinator alongside it to sync them to other devices. Source: about 1 year ago

Other than those you mentioned, there is Warpinator. It works flawlessly for me. You need to create a hotspot manually if there is no internet. Source: over 1 year ago

[Warpinator](https://github.com/linuxmint/warpinator) will do this. I've used it in the past and I just double checked if it will send android to android, which it does. There are packages for Windows and in F-Droid. It is developed by the Linux Mint team, so seems like a trusty source. But, always double check if you are confident in the publisher.
