Transparency!

It is imperative that any sprites uploaded to the Archives (and subsequently edited into Bulbapedia) are made tarnsparent. Transparency means that there is no white block around the image; the image's background automatically becomes whatever color is behind it. Single-color transparency and Alpha channel transparency are simple functions easily accessed on programs such as GIMP and Jasc Paint Shop. LordArceus 18:07, 26 November 2008 (UTC)

...and people should also remember that when they make the sprites transparent, that does not mean only the outer part. I don't remember if all sprites are OK when it comes to Bulbapedia, but many tend to forget the white background not connected to the image edges. Also, Gen III sprites of Shedinja must have an intact crescent thingie; it is often broken since one of the used colors is white.
