IE6 has shockingly bad content detection

Html ends up in exif tags mostly from people adding things like <a href=... to
exif tags

One possible alternative fix (would need review safety of this) i think would
be to have mw modify the file to add 255 bytes of padding (jpg allows padding
markers in file immediately after the first marker. The other case this issue
happens is certain xml formats, which allow whitespace padding).
