Running into a strange issue while setting up meta tags for a summary with large image. The card passes the validator (doesn’t return any errors) but then 404s the image preview.
The url in question is http://biblia.com/books/asv/Jn1.29 and the twitter:image:src tag specifies http://biblia.com/verseoftheday/image/Jn1.29?width=700 as the large image. I’ve checked against size constraints (both dimension and filesize) and don’t see any issues there. The robots.txt is also setup correctly.
Only thing I can think of is a file format issue with the large image registering as a .bmp file and I don’t know if Twitter supports .bmp images. Other than that, any ideas?
