Some themes and/or post types (such as portfolio projects) allow multiple Featured Images to be added to a post, so that those images can be used as a gallery on the single post page. The first/primary Featured Image will be the one used in thumbnails and such, but then added ‘Featured Image 2’, ‘Featured Image 3’, ‘Featured Image 4’, and so on, up to 30 total featured images, to be used as an image gallery for that post.
Is there a way to select 30 images from the media library and assign them ALL as featured images on a single specific post? If not, is there any other way to accomplish this easily? All the images are already in the media library, and they are all organized together by upload date and filename.
Thank you in advance for any support, tips, or suggestions!
