I'm having to get into Twitter to market my products. In the past I paid someone to posted on their twitter products of mine. On clicking it, the far right hand side outside the middle section, in a box section I remember it showed images of the product, links perhaps, not sure if it was showing a section of a web site (iTunes). Its a bit hazy to remember, but I was impressed by it, very handy for adding extra information, short tweet, then to the right the user gets this extra stuff. What was I seeing, how is this done?
I found the tweet. https://twitter.com/cookhealthyfood/status/153985434635079680 Its like its got part of a web page in it. How is this done anyone?
