I have used sharethis plugin in my website. When I shared a particular page it does not crawl the correct image in the share popup window. But after sharing it to the facebook, I can see the correct image. It happens for a particular page only.
I have checked the og:image property and the image meets all its requirement. The dimension of the image is 362x550. I have no idea why it doesn't crawl the image.
Please anyone assist me to get resolve this issue.
Here is the link I shared via sharethis.
Page Link: https://www.getcensored.com/m/photocontest/view/Kassie-Tocko
I can't give you exactly solution, but will try to give you at least some direction.
So what I observed with FB debug tool: https://developers.facebook.com/tools/debug/og/object/
Put initial link https://www.getcensored.com/m/photocontest/view/Kassie-Tocko#st_refDomain=&st_refQuery= and you will see that FB will see your og:image tag
Put some other anchor https://www.getcensored.com/m/photocontest/view/Kassie-Tocko#test1 and click "Fetch new scrape information", you will see a message about parsing error, then try to fetch again and you will see og:image
Try repeat 2. several times with different anchors
I had a similar issue, but the problem was 301 redirect, but you don't have it. May be try disable https and test FB sharing via http, just for test. May be problem is with your SSL negotiation time. Some info related FB and SSL here http://www.webpagetest.org/forums/showthread.php?tid=11788
