The image table describes images and other uploaded files. However, the image description pages are stored like other pages. See also: Manual: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 Manual:$wgHashedUploadDirectory.

| 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.
[edit] img_type
Removed in v1.5.
