As much as I love to hate on apple, any of this format shit is 100% Windows bullshit. It's not just pictures, with shit like webm, or some random video codecs it'll ask you to FUCKING BUY! But even shit like Windows only supporting some like 3 file formats from the god knows how many out there. Ever since I switched to Linux (heck, even fucking MacOS would do better) all this stopped being an issue. Fuck windows for literally only supporting their special selection of formats. There's a good reason why the first step of many people installing windows is also Installing VLC or MUCH superior image viewers. Because Microsoft chooses to not support most things out there!
For most usage, probably nothing. Let's be honest you arent looking at those pics again most of the time. Most of the ones you do, you're looking at on your phone which has a tiny screen. Ask yourself how many times you've wanted to zoom in 10x on a jpeg on your computer and there's your answer as to whether there's anything wrong with it.
It’s a 32 year old format that makes pictures worse in order to save space. A lot changes in the tech works in 30 years. While there may be nothing inherently wrong with it, there’s far better image encoding algorithms these days that can store images in less space without reducing the quality as much.
Almost all of them? They may prompt you to install additional codecs but thats it. Most software displaying images support thoose image formats. Man we have vlc to display any format
That's exactly the same case as Windows. The built-in photo/video players don't support them out of the box, but do if you install the free codec from the store, or you can install any 3rd party players you like.
There are lots of great things about Linux, but out of the box support for licensed video codecs isn't magically better than Windows
