Template:Bad JPEG
 | This image was uploaded in the JPEG format even though it consists of non-photographic data. The information it contains could be stored more efficiently or more accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image, derived from a non-JPEG source so that it doesn't contain any compression artifacts (or with existing artifacts removed) and with transparency where appropriate. After doing so, please replace all instances of the JPEG version throughout Wikipedia (noted under the "File links" header), tag the JPEG version with {{obsolete|NewImage.ext}}, and remove this tag.
