Why did you make the image file format default to JPG? There are next to none jpeg format image files, if any, at least I can't find any File entries in the history for the past 30 days / 500 entries. Resulting in disabling any item template on the wiki showing an image.
The portable network graphics format has been used throughout the wiki, they're of good image quality and moderate file size if the [[images]] are saved correctly. I can't see a lot of jpeg format files being uploaded any time soon. A consistent transition would be if the existing png image files were converted and uploaded in advance instead. But then again, for what reason? --[[User:Ulviirala|Ulviirala]] 21:42, 24 May 2010 (UTC)
I changed it based on the following correspondence with MrBloodworth:
== Added decoration and storage params, made switches case-insensitive, combined with Template:ItemM ==
I was asked to make this change, I tested it a lot and there are no pages I can find that look any different or are broken unless the new parameters are used. I also combined [[Template:ItemM]] with this one so the fences no longer need their own template. If there are any objections please say so. --[[User:NESGamepro|NESGamepro]] ([[User talk:NESGamepro|talk]]) 15:18, 18 August 2013 (CEST)
