Request - export of album cover file extension - change to .jpg

[kentucky_slim]

Hi, first of all great app! It's been very useful for hard to manage pieces of my collection that other apps can't do.

Is it possible to change or at least select the file extension name when exporting the embedded album cover for songs? Currently it outputs as .jpeg which is not recognized by MPD. Would be awesome if it could be either selected or automatically dump the image as .jpg.

Thank you!

The export uses the information stored in the tag and in this case the mime type
I could use the 'Filename format' value provided by the user and an option to not output the extension automatically

Will add to my TO-DO list for now and possibly get a new beta out since i am in the process of migrating compilers
