I know its too late for this answer, but can help others, you can use Media Deduper plugin to index and find duplicated image , it is also good enough to link the post to existing image.
Contrary to Pieter, I’d say your if statement is correct (although, unnecessary). If it’s a WordPress theme, then add_theme_support will likely exist! Have you per chance added the images before setting the post thumbnail size? If so, you need to regenerate your images: http://wordpress.org/plugins/regenerate-thumbnails/
First, please don’t use query_posts() (emphasis mine)! Note: This function isn’t meant to be used by plugins or themes. As explained later, there are better, more performant options to alter the main query. query_posts() is overly simplistic and problematic way to modify main query of a page by replacing it with new instance of the … Read more

I have the same issue with not being able to turn off big_image_size_threshold (one of the worst new features WordPress has ever put out) for kicks I tried removing the quotes around return false but it doesn’t resolve the issue. The example in Codex does in fact show quotes. https://codex.wordpress.org/Function_Reference/_return_false I have opened a ticket … Read more
even if you had included the all of the needed files you will still have to create your some extra hidden fields like _nonce to pass the check_ajax_referer( “set_post_thumbnail-$post_ID” ); also you would need to create an action hidden field to identify the case of Ajax call with the value : “set-post-thumbnail” You are better … Read more
Answers: Is post_guid the image location reference? Or is the path to the image stored somewhere else? $post->guid is the record in a post which holds the URL for your attachment. Where is featured image set? featured image is saved as post meta so use update_post_meta() once you have the attachment id: update_post_meta( $post->ID, ‘_thumbnail_id’, … Read more
