The problem is probably not with the theme but the meta info of the pictures, the script lacks the important part where _wp_attachment_metadata is updated and different sizes of thumbnail is created, this is done by doing
$attach_data = wp_generate_attachment_metadata($attach_id, $filepath);
One other issue with the add-on is that it is running quite late in the process, I did modify it heavily and inserted it to run during the drip of the post, as i need other plugins to have the featured_image (automatic posting to facebook, Pinterest....), after a lot of searching I found out that I also needed to set the post in draft mode during the drip and then insert all of the data for featured image and after that change it to published.
I inserted my code (alot modified from the one in the post) on line 4494 in datafeedr.php, will not slow down the pages for your visitors. If anyone needs more assistance with this please PM me..
