In the picture, the first posted by the veteran star since having a heart valve replaced in New York last week, he poses in a park dressed casually in a cap, jeans and shirt.
He captioned the photo: “A walk in the park!” It comes after the Rolling Stones frontman, 75, told fans this week he was “on the mend” after his operation.
He wrote: “Thank you everyone for all your messages of support.
“I’m feeling much better now and on the mend.
“Also, a huge thank you to all the hospital staff for doing a superb job.”
His heart problem was picked up during a medical ahead of the band’sMick is still 17-date No Filter tour across the US and Canada.
It was due to start in Miami next month but the diagnosis meant the tour was halted and is set to be rescheduled.
As much as £200million had been spent on tickets by about a million eager fans.
It is understood the singer is aiming to be back on stage with the band by the summer.
When the postponement was announced, Sir Mick tweeted: “I’m so sorry to all our fans in America & Canada with tickets. I really hate letting you down like this.
“I’m devastated for having to postpone the tour but I will be working very hard to be back on stage as soon as I can.
“Once again, huge apologies to everyone.”
After posting the picture yesterday, Sir Mick was inundated with messages from well-wishers.
One delighted fan replied: “Looking great, Mick. Hope you’re doing well.”
Another added: “Happy to see you back in action Mick!
“Hoping to see you soon here in Brazil.”
The Stones revealed that Sir Mick had been advised not to go on stage weeks before the tour was due to start.
The procedure he undertook is known as trans-catheter aortic valve replacement, or TAVR.
TAVR is being used more frequently as an alternative to a surgical valve replacement, which requires the chest to be opened.
It allows for shorter hospital stays and quicker recovery times.
Sir Mick has continued touring and giving energetic performances well into his old age, playing the Glastonbury Festival in 2013.
But he also has a busy family life with eight children, five grandchildren and a greatgranddaughter.
He is dating 32-year-old Melanie Hamrick. The American ballerina is the mother of his youngest son Deveraux, two.
