I have recently been uploading from dvidshub.com, and noticed several files where the EXIF data is wrongly displayed. Checking the original files, the EXIF displays perfectly well in photo processing tools.
Example:
File:An Air Force Chief - 39 years old - Army Ranger School - Why not? (Image 1 of 3) 160519-F-HA938-001.jpg
The camera model should display as "Nikon D4", and make as "NIKON CORPORATION", however seems to have been overwritten by a description. The error may lie in the use of auto linking as the corrupt text is shown as English Wikipedia links.
