Jagged Miniskirt

So I was in the process of replacing the Jagged Mini Skirt pictures with png versions, when I realized I needed to add "Equipped" to the filename for the template, and that was when I realized that the previous png versions had been deleted, so now I'm not so sure about replacing them anymore.

Is there something special about the pictures already there? Or were the previous png versions deleted because of something else?

It would be preferable if you did replace the jpgs with pngs.

Previous pngs were probably deleted due to policy violation and jpg might have been what we had leftover. It's fine it you replace jpgs with pngs (of course as long as they abide policy)
