[feature request] - (Photos in JPG format on RetroArch)

[AlanRibas]

Would it be possible to add the possibility for RetroArch to recognize images with the extension .JPG and also of any size?

I currently own all the box arts in the games. But they were collected all over the internet and being of different sizes. Currently, only PNG format photos are accepted in RetroArch. Would adding compatibility with .JPG files be complicated?

It could be added to the retroarch desktop menu, right where we load and drop images of the games, a button so that we could search for the address where the images of the game covers are. This would make the configuration of this part much easier.

I made a stupid drawing just to illustrate the idea.
