By this stage, the idea of sharing a picture to Instagram is old hat for most people, but now one of the world's most recognisable women has jumped on board - Queen Elizabeth II has just posted her first picture to the site.
The United Kingdom's head of state shared the post to the official Royal Family account today, during a visit to the Science Museum in London.

During her visit, Liz took a snap of a letter written by her great-great-grandfather Prince Albert, dating back more than 170 years.
The caption to her pic said: "Today, as I visit the Science Museum I was interested to discover a letter from the Royal Archives, written in 1843 to my great-great-grandfather Prince Albert.
"Charles Babbage, credited as the world's first computer pioneer, designed the 'Difference Engine', of which Prince Albert had the opportunity to see a prototype in July 1843.
"In the letter, Babbage told Queen Victoria and Prince Albert about his invention the 'Analytical Engine' upon which the first computer programmes were created by Ada Lovelace, a daughter of Lord Byron.
"Today, I had the pleasure of learning about children's computer coding initiatives and it seems fitting to me that I publish this Instagram post, at the Science Museum which has long championed technology, innovation and inspired the next generation of inventors."

The post was signed 'Elizabeth R'.
Since HRH posted the pic, it has received more than 25,000 likes and hundreds of comments.
The Science Museum thanked the Queen for coming to open The Smith Centre at the museum, with their social media team writing that they were 'honoured' she chose it as the subject of her first ever Instagram post.
They wrote: "We're thrilled that the image is of correspondence from the Royal Archive between Charles Babbage and Your Majesty's great-great grandfather Prince Albert about the Difference Engine No.1 on display in our Making the Modern World gallery.
"We'll be celebrating the long relationship between the museum and the Royal Family on our Instagram Stories throughout the day."

But they're not the only ones who were pleased to see Her Majesty get involved.
One fan wrote: "The Queen's first Instagram post, my heart! Love it!!"
A second follower said: "I'm an American and I get the privilege of commenting and liking a direct post from the Queen of England. Honestly, this made my day. Thank you!"
While a third person added: "Welcome to Instagram Your Majesty. Truly an honour to read your post."
