wp media regenerate

Regenerates thumbnails for one or more attachments.

OPTIONS

See the argument syntax reference for a detailed explanation of the syntax conventions used.

[<attachment-id>...]

One or more IDs of the attachments to regenerate.

[--image_size=<image_size>...]

Name of the image size to regenerate. Repeat the flag to specify multiple. Only thumbnails of specified image size(s) will be regenerated, thumbnails of other image sizes will not.

[--skip-delete]

Skip deletion of the original thumbnails. If your thumbnails are linked from sources outside your control, it's likely best to leave them around. Defaults to false.

[--only-missing]

Only generate thumbnails for images missing image sizes.

[--delete-unknown]

Only delete thumbnails for old unregistered image sizes.

[--update-attachment-refs]

Update references to regenerated thumbnails in post content.

[--yes]

Answer yes to the confirmation message. Confirmation only shows when no IDs passed as arguments.
