Glad you continue to participate :)

You know, that's true PNG pictures are always cool to make thumbnails, but other pictures can be cool sometimes too, look for instance at the official Darth Vader VS Doctor Doom picture, the Ho-OH vs Phoenix thumbnail made by PuasLuisZX in the first season or even GBA's Sonic VS Goku in Season 2. PNGs aren't an obligation, even if I admit it can make things easier ^^
