Message:

Save progress of intermediate image creation after upload. First run.

  • Introduces wp_get_missing_image_subsizes() and wp_update_image_subsizes() to generate image sub-sizes that are missing or were not created after the upload.
  • Adds a way to display errors that happened while creating sub-sizes.
  • Introduces wp_create_image_subsizes() intended for use after an image was uploaded. It saves/updates the image metadata immediately after each sub-size is created. This fixes the (long standing) problem when some of the sub-size image files were created but there was a timeout or an error and the metadata was not saved. Until now such uploads were considered "failed" which usually resulted in the user trying to upload the same image again, creating even more "orphan" image files.

Note that the patch also includes some unrelated WPCS fixes.

Props mikeschroder, azaozz.
