how to make custom spray with gimp?

[TheOrangeGrape 48]

Hey so I've been wanting to get a custom spray for a while, I know you have to change it to a .vtf file but I don't know how to do that, even with gimp. Does anyone know how to change it from .jpeg to .vtf using gimp or anything else?

There are links to plugins for GIMP, Paint.NET, Photoshop, and VTFEdit in that thread.
