Thank you so much! The photo practically manipulated itself - it's from the Season 3 behind-the-scenes promo shots, and Ben and Martin are laughing over script pages. They looked so adoring, that I could almost see the baby there! :)

Here's a link to the original photo: http://media2.onsugar.com/files/2013/09/20/847/n/1922507/a1640cba86feb2ab_p01h0s64.preview.jpg

(The image of Mrs Hudson came from the scene in Scandal where Sherlock says, "Mrs Hudson leave Baker Street? England would fall!")
