In Wordpress, we have added our own intermediate image sizes to the standard Wordpress sizes using add_image_size().
Using our own admin interface to upload images, we then use wp_generate_attachment_metadata() to create all thumbnails and save them to a predefined folder on the server.
However, we would like to restrict wp_generate_attachment_metadata() to generate our custom defined image sizes ONLY and ignore the Wordpress standard sizes.
Is this possible?
Thanks in advance for any help!
