I have a multisite instance that has several blog templates through the New Blog Template plugin. The images on the multisite instance have been offloaded via Offload S3 and are served through Cloudfront, so no images are stored in the WP uploads folder. We're also using one of the subdomains as a global media library that points to the Cloudfront images for all the other subdomains to use.
As an example, http://demo-pottershand.outreachapps.com is the blog template, and the images are served through the cdn with the url structure: "http://images.outreachapps.com/wp-content/uploads/sites/53/2018/02/17000807/lightstock_250027_medium_user_43208115.jpg". Site 53 is the global media library that is being used to point to S3/Cloudfront and http://demo-pottershand.outreachapps.com is using the image urls that it generates to populate the images in its template. When a new blog is generated, the image url changes to "http://harmonybaptistchurch.outreachapps.com/wp-content/uploads/sites/53/2018/02/lightstock_250027_medium_user_43208115.jpg" when it should be: "http://images.outreachapps.com/wp-content/uploads/sites/53/2018/02/17000807/lightstock_250027_medium_user_43208115.jpg". If the URL was to stay the same, the Offload S3 plugin could filter to the appropriate url, but since the url changes to include the new subdomain, this isn't possible.
Does somebody know how to have the New Blog Template plugin not replace the URL structure of anything that includes the "uploads" folder? Based on what I've seen in past threads, this may have been classified as a bug in the past, but I need this feature ASAP.
Your help would be much appreciated! Thanks.
