The fields are:
 * img_name: Filename.
 * img_size: File size in bytes.
 * img_description: Description field given during upload.
 * img_user: User ID of who uploaded the file.
 * img_user_text: User name of who uploaded the file.
 * img_timestamp: Timestamp of when upload took place.
 * img_sha1: The SHA-1 hash of the file contents in base 36 format. includes/GlobalFunctions.php's wfBaseConvert is used to convert from base 16 (hexadecimal) to base 36 and then pad the result to 31 characters.

Some of this information was adapted from  in the MediaWiki   directory.
