Created attachment 8194 [details] Original file from: http://upload.wikimedia.org/wikipedia/commons/6/6a/Jan_hoet.jpg (looks fine for me) Some thumbnails (for now I could only find [[commons:File:Jan_hoet.jpg]] are negative. Extracted EXIF info with Apple Preview: { ColorModel = CMYK; DPIHeight = 300; DPIWidth = 300; Depth = 8; Orientation = 1; PixelHeight = 1299; PixelWidth = 880; "{Exif}" = { ColorSpace = 65535; PixelXDimension = 880; PixelYDimension = 1299; }; "{JFIF}" = { DensityUnit = 1; JFIFVersion = ( 1, 2 ); XDensity = 300; YDensity = 300; }; "{TIFF}" = { Compression = 1; DateTime = "2010:07:03 20:26:34"; Orientation = 1; PhotometricInterpretation = 5; ResolutionUnit = 2; Software = "Adobe Photoshop CS3 Windows"; XResolution = 300; YResolution = 300; }; } Extracted Metdata by MediaWiki: == Metadata == Width 2,121 Height 3,132 Compression scheme Uncompressed Pixel composition 5 Orientation Normal Number of components 4 Horizontal resolution 300 dpi Vertical resolution 300 dpi Data arrangement chunky format Software used Adobe Photoshop CS3 Windows File change date and time 20:26, 3 July 2010 Color space 65535

Both affected images are: *CMYK images *Have the exif color space tag set to uncalibrated (65535=uncalibrated) Thus, sounds like upstream issue/dupe of bug 24854. In the mean time, maybe convert to rgb, and re-upload. *** This bug has been marked as a duplicate of bug 24854 ***
