Why did this hap­pen now? We’ve had update_with_media on Twitter via the API since August 2011, so you could upload pic­tures for a long time. We got a ​“rich pho­to expe­ri­ence” in September [2013]. […] But the short answer is I don’t know why we’ve had this capa­bil­i­ty for a year and nobody’s done any­thing with it until now in terms of trans­form­ing image bots.
