I'm new to Sitecore and I'm looking for the details of media library pipelines in CD. I'm trying to redirect media library link based on a flag. If the flag is checked for media library item then it should redirect to a page. We wont be able to depend on scheduled publishing since the number of media items is to huge(200-300 media items). So we need to publish the items and keep it as non accessible till the flag is un-checked.
Thanks in advance.
