So, I'm testing Twitter and Facebook sharing features.
I am currently testing the Twitter share button, I have added meta tags, and after several hours of searching, I have found that it is possible for me to embed tweets (embed twitter images in my tweets that link back to my website) I need Twitter cards.
My meta code:
<meta name="twitter:card" content="summary_large_image"> <meta name="twitter:site" content="http://MY_IP_ADDRESS:3000/"> <meta name="twitter:creator" content="@random"> <meta name="twitter:title" content="Parade of Fans for Houston's Funeral"> <meta name="twitter:description" content="NEWARK - The guest list and parade of limousines with celebrities emerging from them seemed more suited to a red carpet event in Hollywood or New York than than a gritty stretch of Sussex Avenue near the former site of the James M. Baxter Terrace public housing project here."> <meta name="twitter:image" content="http://cdn0.lostateminor.com/wp-content/uploads/2015/10/Amazing-long-exposure-photos-make-light-look-like-cobwebs-on-trees2-650x434.jpg">
Then a sharing button that looks like this:
<img src="http://cdn0.lostateminor.com/wp-content/uploads/2015/10/Amazing-long-exposure-photos-make-light-look-like-cobwebs-on-trees2-650x434.jpg"> <a href="https://twitter.com/intent/tweet?button_hashtag=test" data-url="http://localhost.share.com/" target="_blank">Tweet #test</a> </img>
When I tweet a hash tag, it doesn't display my image or tweet it. So I tried to launch my site (I am testing it on my localhost on Twitter Card Validator) https://cards-dev.twitter.com/validator .
I get this error message: 
Any ideas what I did wrong? Or why can't I use my IP address so that I can check Twitter maps?
Thanks!
