Add jpg format for artwork.

[PrettyPrincess]

Nearly all of my artwork is in .PNG format. But i have a few things in .JPG format which doesn't display anything. Could we please get support for .JPG files?

I would advice you to use a little JPG to PNG converter, there are tons available! Here is one for example:https://pnggauntlet.com/
This question has been asked sometimes and I think that the reply was: PNG only for now!
