class FileRemoteImage in Migrate Files (extended) 8

Create an image file entity with a remote url without downloading the file.

This is almost the same as file_remote_url except it supports supplying a width and height for the image for image fields. This will prevent the image module from requesting the image file to measure the width and height which can slow down migrations with lots of remote images.

Available configuration keys:

• uid: (optional) The uid to attribute the file entity to. Defaults to 0.
• width: (optional) The width of the image(s)
• height: (optional) The height of the image(s)

Example:

destination:
  plugin: entity:node
process:
  field_image:
    plugin: file_remote_image
