We have a offload plugin that offloads image to the CDN. The plugin removes the images after offloading to the CDN. The problem is we cannot generate more thumbnails as the images are not in the server. Now, we wanted to download again to the server from the CDN for us to generate thumbnail on the featured images but we don’t know how to filter the media library to featured images only.

We are trying to find a solution that filter the media library images for featured images only so that only the featured images are downloaded and not the entire images. (We only need featured)

We are looking for something like this because we think that it can be filtered through URL.
