మూస:Artifacts - వికీపీడియా

This image was uploaded in the PNG, GIF or other lossless image format. However, it contains visible lossy compression artifacts. These artifacts may have come from the JPEG format or from saving a colorful image in the GIF format instead of the PNG format.
If possible, please upload a PNG or SVG version of this image, derived from a non-lossy source so that it doesn't contain any compression artifacts (or with existing artifacts removed). After doing so, please replace all instances of the artifacted version throughout Wikipedia (noted under the "File links" header), tag the old version with {{obsolete|NewImage.ext}}, and remove this tag. For more information, see Wikipedia:Preparing images for upload.
