You can't save you're made preset as .JPEG file, 'cause it will never work.
You can only save it as .PNG file.
If you're new to making presets, I'd suggest you start of with Preset 1 and 2.
Good luck, my friend! ^.^
Anytime! ^.^
PM me if you have any other problems! ^.^
Good luck, again my friend! ^.^
