Handbuch:image-Tabelle
↑ Handbuch:Inhaltsübersicht | MediaWiki-Datenbank-Layout | image-Tabelle |
The image table describes images and other uploaded files.
However, the image description pages are stored like other pages.
Siehe auch: Verwalten von Bildern.
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 .

T155741
img_bits
MediaWiki Version: | ≥ 1.5 |
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
MediaWiki Version: | ≥ 1.5 |
Möglichkeiten sind: UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, ARCHIVE, 3D
img_major_mime
MediaWiki Version: | ≥ 1.5 |
Möglichkeiten sind: unknown, application, audio, chemical, image, message, model, multipart, text, video
img_minor_mime
MediaWiki Version: | ≥ 1.5 |
z.B. jpeg, gif, png, svg+xml, tiff, ogg, pdf vnd.djvu, webm, wav, mpeg, x-flac, midi, x-xcf, sla, webp, etc.
img_description
MediaWiki Version: | ≤ 1.32 |
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.
(veraltet); imgcomment_description_id of the image_comment_temp
table and the comment
table should be used instead!
img_description_id
MediaWiki Version: | ≥ 1.30 |
This is a foreign key to comment_id in the comment table.
img_user
MediaWiki Version: | ≤ 1.33 |
User ID of the user who uploaded the file.
(veraltet in 1.31)
While Actor-Migration is being done, and depending on the configuration setting $wgActorTableSchemaMigrationStage
, this field may be empty and the actor performing the edit can be stored in the img_actor field instead.
img_user_text
MediaWiki Version: | ≤ 1.33 |
User name of the user who uploaded the file.
(veraltet in 1.31)
While Actor-Migration is being done, and depending on the configuration setting $wgActorTableSchemaMigrationStage
, this field may be empty and the actor performing the edit can be stored in the img_actor field instead.
img_actor
MediaWiki Version: | ≥ 1.31 |
This is a foreign key to actor_id in the actor table and specifies the actor who uploaded the most recent version of the image.
img_timestamp
Timestamp of when upload took place. Not necessarily the same timestamp as logging.log_timestamp.
Except for image revisions imported from another wiki, the timestamp uniquely identifies the file revision. If two uploads of the same file happen in the same second, the latter one is delayed until it gets a different timestamp.
img_sha1
MediaWiki Version: | ≥ 1.11 |
The SHA-1 hash of the file contents in base 36 format. Wikimedia\base_convert()
is used to convert from base 16 (hexadecimal) to base 36 and then pad the result to 31 characters.
img_type
MediaWiki Version: | ≤ 1.4 |
