changing profile pic

Just noticed that my profile pic is not the one I want.  For the life of me, i can't seem to find out how to change it.  Thnx for the help!

Go to your 'my profile' page.
Click on "General info about myself"
On that page, there will be a line for picture.
Enter the source of the picture into the blank space.
Hit the "Submit" button at the bottom of that section.

That should do the job.
