[twitter] Twitter - share button, but with image

I want to use regular share button like on this page https://twitter.com/about/resources/buttons#tweet but to add an embedded image from my site, not just link.

I know all about 1.1 api and uploading, but making an tw application and then ask visitor on my site to give permission to write on his timeline just to share one pic from my site is not likely scenario, so I think about alternatives.

I've noticed when just paste links of pic that are already uploaded on twitter into tweet, if you paste link like https://pbs.twimg.com/media/BPpk_KUCMNBXsPN.jpg that is not going to be embeded, but if you paste link like this pic.twitter.com/NuDSx1ZKwy it will be embeded. So I think if I make profile and app that will call https://upload.twitter.com/1/statuses/update_with_media.json and upload pic, and then paste link in share button I will get tweet with pic embeded. Or there is better way? I use php.

To create a Twitter share link with a photo, you first need to tweet out the photo from your Twitter account. Once you've tweeted it out, you need to grab the pic.twitter.com link and place that inside your twitter share url.

note: You won't be able to see the pic.twitter.com url so what I do is use a separate account and hit the retweet button. A modal will pop up with the link inside.

You Twitter share link will look something like this:

<a href="https://twitter.com/home?status=This%20photo%20is%20awesome!%20Check%20it%20out:%20pic.twitter.com/9Ee63f7aVp">Share on Twitter</a>

Look into twitter cards.

The trick is not in the button but rather the page you are sharing. Twitter Cards pull the image from the meta tags similar to facebook sharing.

Example:

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@site_username">
<meta name="twitter:title" content="Top 10 Things Ever">
<meta name="twitter:description" content="Up than 200 characters.">
<meta name="twitter:creator" content="@creator_username">
<meta name="twitter:image" content="http://placekitten.com/250/250">
<meta name="twitter:domain" content="YourDomain.com">

I used this code to solve this problem.

<a href="https://twitter.com/intent/tweet?url=myUrl&text=myTitle" target="_blank"><img src="path_to_my_image"/></a>

You're right in thinking that, in order to share an image in this way without going down the Twitter Cards route, you need to to have tweeted the image already. As you say, it's also important that you grab the image link that's of the form pic.twitter.com/NuDSx1ZKwy
