Manual:Contents MediaWiki database layout image table


The image table describes images and other uploaded files. However, the image description pages are stored like other pages. See also: Image Administration. Many of the fields in this table are analogous to those in the oldimage table. Some of this information was adapted from schema.doc in the MediaWiki docs/ directory.

The path for the actual image is not stored in this table: see $wgHashedUploadDirectory.

Timestamp of when upload took place. Not necessarily the same timestamp as logging.log_timestamp.

img_sha1[edit]

MediaWiki version: 1.11

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.
