|#45 • Whether to keep both PNG and GIF images versions of game sprites, Wildgoosespeeder (ended December 19)|
Special:Log/delete/L151 - It was decided that the animated GIFs shouldn't be deleted. Static GIFs and duplicate animated GIFs are exempt. Static GIFs should be replaced with PNG anyways (File:Starbeans.gif and File:MLSS Starbeans Cafe Menu.png). Duplicate animated GIFs should be deleted (File:PeteyTime.gif and File:Petey Piranha Ground Idle.gif).
