Hi Artsee7, you can just copy your link and post it to your twitter page. If you want the picture to appear, you need to install this plugin – https://wordpress.org/plugins/wonderm00ns-simple-facebook-open-graph-tags/
Hi Rachel, i have installed the plugin and check some settings for twitter, and i pasted a code onto my header.php (not sure whether is it correct). After tat is there anything else i should do ?
Go through the settings and start posting on Twitter. It should be okay as its quite straight forward.
