Forum:Strange image compression?

Hi, I've recently noticed a number of subtle changes concerning images on wikia. One of these is an occurrence where an image is uploaded to a wiki, in this case the Full Metal Panic! wiki and after being used in an article it appears pixelated and with a small degree of noise. Compare this with this one. Here, the first image appears fine but the second has the above changes after being used on the main page slider. Is it possible to prevent this happening? Any help would be appreciated. Kozakuu 14:42, March 24, 2012 (UTC)


 * I don't see a difference, try purging by going here to force the page to reload, then purge it. Thanks, Iggyvolz 14:51, March 24, 2012 (UTC)
