1️⃣ Describe the feature

As stated in a 2023 comment of an issue, and many other issues like that, IG uses ImageMagick to display images, and it would be nice if it had all supported ones by default, rather than the user adding them everytime they install it.

2️⃣ How to use feature

1. Add many extensions like j2k, jpf, jpm, jps, jpx, mng, pns, svgz (and possibly more?) to the defaults.

3️⃣ Additional context

Hmmm, long time ago, people complained about the file formats that were auto-associated. Plus, I don't fully test all supported extensions of ImageMagick, so having a setting to let users to add/remove the formats is good for now.
