Amitabh Bachchan has thanked his extended family (EF) for finding the original morphed image of his new-born granddaughter's picture.

His daughter-in-law Aishwarya Rai gave birth to her and husband Abhishek's first child Nov 16. The Bachchans shared the news on Twitter, but refused to post the baby's picture on-line, saying it is a private matter.

Meanwhile, someone posted a morphed picture of the baby on the net.

"Ladies and gentlemen of the EF world, I present to you the picture being circulated and below that, the original from where the morphing was done. A smart piece of work!! Not the morphing. The diligence of our EF team," Big B posted on his blog.

"I have to say that the EF was incredibly smart! How on earth were they able to search for the original beats me. Well done dearest ones !!," he added.

The picture of Aishwarya's baby girl has been doing the rounds on internet for the past few days and this has upset the Bachchan clan.

Also the 69-year-old received several requests for the baby's picture, but he refused.
