There is an option to add user image/photograph under User Accounts in System Settings. But whenever I try to add an user image, the system settings freeze and I have to kill it using xkill command. But after that till I restart my computer I can't reopen my system settings.
Please let me know the solution of this problem.

Easy: convert your picture (using any picture program like gimp) to a square .png and save it somewhere where all users have access.
Then use that one in the Add User Image...
