Lol thats funny . I dint know coz last I changed my pic was 6 months ago.

Anyways, I figured out the issue.

I was trying to set profile pic using an image which I had received in Wazapp from a friend. It turns out that that the image had a VERY LONG name , hence it was failing. I tried renaming it , and even that did not help. The I used a different one, and I worked. So it seems that the image was not being accepted by Whatsapp , or Wazapp, I dont know which.

Do we know of any minumum and maximum size requirements for profile pictures for Whatsapp?
