The Spin-Off you've all been waiting for is finally here! https://twitter.com/Team_Barrowman/status/733319373432229888/photo/1?ref_src=twsrc^tfw
He also recorded something with Katy Manning. Captain Jack meets Iris Wildthyme; the mind boggles at the thought of that much Camp in one room... Basically Big Finish seem to have taken advantage of him being back in the UK for a while to record a bunch of stuff with him as opposed to doing it over Skype as they've had to so far.
Frankly, if Jack hadn't said "hello" to Jackie at some point, repeatedly (sometimes in French) I would be disappointed in both of them.
Jackie: "I'm in my dressing gown." Jack: "Yes, you are." Jackie: "There's a strange man in my bedroom." Jack: "Yes, there is." Jackie: "Well, anything could happen." Jack: "You bet."
To update: he recorded a three story full-cast (finally) Torchwood box set for release in November plus four other non-TW stories to be revealed later.
Well it was Jack, Ianto, Gwen, Rhys and Andy as the main cast, so either she was misquoted or changed her mind. And as if by magic: https://www.bigfinish.com/news/v/torchwood-outbreak-coming-november-2016
Big Finish announced their Torchwood slate for next year, and among the entries is "The Lives of Captain Jack". That would seem to be the source of the pic in the OP. https://www.bigfinish.com/releases/v/the-lives-of-captain-jack-1519
