Normally to convert the screenshots from KotOR I have to open them all in photoshop and save them individually as JPEG's. Since ConvertShots mirrors the images and I had a spare half an hour i decided to throw this together to quickly save all the images in a specified directory as a separate JPEG.
I was going to throw in a "Delete original TGA's" but I forgot and don't fancy making changes. All I can advise is; change "View" in explorer to "Tiles" and arrange by name, the JPEG's line up on the one side and the Targa's the other
Alternatively, arrange by file type...
