Manual:Image table/es
The image table describes images and other uploaded files.
However, the image description pages are stored like other pages.
Véase también: Administración de imágenes.
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.
Campos
img_name
Nombre de archivo usando guiones bajos.
img_size
Tamaño del archivo en bytes.
img_width
| Versión de MediaWiki: | ≥ 1.5 |
Ancho de la imagen, en píxeles.

Serialized file's properties, as PHP array serialization or as JSON.
The json array can contain an address in the text table or external storage.
0, -1 or blank if the extractor fail.
T155741
img_bits
| Versión de MediaWiki: | ≥ 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
| Versión de MediaWiki: | ≥ 1.5 |
Las posibilidades son: UNKNOWN, BITMAP, DRAWING, AUDIO, VIDEO, MULTIMEDIA, OFFICE, TEXT, EXECUTABLE, ARCHIVE, 3D
img_major_mime
| Versión de MediaWiki: | ≥ 1.5 |
Las posibilidades son: unknown, application, audio, chemical, image, message, model, multipart, text, video
img_minor_mime
| Versión de MediaWiki: | ≥ 1.5 |
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
| Versión de MediaWiki: | ≤ 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.
(desaprobado); imgcomment_description_id of the image_comment_temp table and the comment table should be used instead!
img_description_id
| Versión de MediaWiki: | ≥ 1.30 |
This is a foreign key to comment_id in the comment table.
img_user
| Versión de MediaWiki: | ≤ 1.33 |
User ID of the user who uploaded the file.
(desaprobado en 1.31)
While Migración de actor 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
| Versión de MediaWiki: | ≤ 1.33 |
User name of the user who uploaded the file.
(desaprobado en 1.31)
While Migración de actor 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
| Versión de MediaWiki: | ≥ 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
| Versión de MediaWiki: | ≥ 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
| Versión de MediaWiki: | ≤ 1.4 |
