This image was uploaded in the PNG image format. However, it contains visible lossy compression artifacts. These artifacts may have come from the JPEG format, from saving a single colorful image as GIF instead of PNG or from saving an animated GIF using the incorrect settings (See also Dither). If possible, please provide a superior version of this file, derived from a non-lossy source (or with artifacts removed). If applicable, please replace all instances of the artifact version throughout Wikimedia projects, tag the old version with one of these templates, and remove this tag.
