I had to remove all the markers from the JPG file before mediawiki upload would accept it. [[Bugzilla:16583]] "MIME type detection of "application/x-php" gives false positives on any file with "<?" in it" describes a similar problem, that might have the same cause as this one, except the first "<?" in the Shimon_Peres image does not appear until byte 16401. Note I have since uploaded two versions of the image.

Note: this particular image file was finally uploaded together with its EXIF and IPTC data by manually editing the embedded HTML code: "<a href" and "</a>" changed to "[a href" and "[/a]" respectively. The first "<a href" occurred at byte 407.
