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

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

img_name
Filename using underscores.

img_size
File size in bytes.

img_width
Image width, in pixels.

img_height
Image height, in pixels.

img_metadata
Serialized file's properties, as PHP array serialization or as JSON. ,  or blank if the extractor fail. T155741

img_bits
Bit-depth of GIF/PNG palette-based images (up to 8-bit). Non-palette images (JPEG/PNG/TIFF/SVG) are 0, 8, or 16. All other files default to 0.

img_media_type
Possibilities are: UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, ARCHIVE, 3D

img_major_mime
Possibilities are: unknown, application, audio, chemical, image, message, model, multipart, text, video

img_minor_mime
E.g. jpeg, gif, png, svg+xml, tiff, ogg, pdf	vnd.djvu, webm, wav, mpeg, x-flac, midi, x-xcf, sla, webp, etc.

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


 * of the image_comment_temp table and the comment table should be used instead!

img_description_id
This is a foreign key to in the  table.

img_user
User ID of the user who uploaded the file.

While is being done, and depending on the configuration setting , this field may be empty and the actor performing the edit can be stored in the img_actor field instead.

img_user_text
User name of the user who uploaded the file.

While is being done, and depending on the configuration setting , this field may be empty and the actor performing the edit can be stored in the img_actor field instead.

img_actor
This is a foreign key to in the  table.

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

img_sha1
The SHA-1 hash of the file contents in base 36 format. is used to convert from base 16 (hexadecimal) to base 36 and then pad the result to 31 characters.
