Posting images is not helpful as it makes it difficult to copy and paste URLs.
You posted an image with a reference for
twitter:image content with a Weebly.com link - if you then check the robots.txt file for that domain it blocks crawlers.
This is very difficult to spend time on when the basic links are blocking access to the data you want to show in cards. Sorry but please work with your host before asking us to spend time debugging. Thank you.
