Are there changes on how image files are handeled? I have two .PNG files on the main page on magicduels.wikia, which were uploaded on October 23 with a resolution of 300 x 195 px. Today I noticed that both of these are blurred. Checked on the resolution and while on the file page it says they still are 300 x 195 px, the actual resolution of the file was changed to 200 x 130 px.

I went ahead and reuploaded one of them and violà! the image was displayed correctly again. Left the other one untouched, in case someone needs to see the difference. Can provide screenshots if needed. I would appreciate any kind of hint or help.
