The image table describes images and other uploaded files. However, the image description pages are stored like other pages. See also: Manual:Image Administration.
[edit] Fields
- img_name
- Filename.
- img_size
- File size in bytes.
- img_width
- ??
- img_height
- ??
- img_metadata
- Serialized PHP array of the file's properties.
- img_bits
- Bit-depth of GIF/PNG palette-based images (up to 16-bit). Non-palette images (JPEG/PNG/TIFF/SVG) are 0 or 8. All other files default to 0.
- img_media_type
- ??
- img_major_mime
- ??
- img_minor_mime

- img_description
- Description field given during upload. It's not the desciption page (associated File: wiki page), but the "summary" provided by the user in case of reupload.
- img_user
- (Manual:User_table) 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.
