membership with pictures

Hi 
I like to add a picture when visitor creating an account on my web site. I was wondering If any of you already tried that if so share the snippet or ideas. 
I thought about creating another table on the server and uploading the pictures there. But I think images can be uploaded to user table under aspnetuser membership tabes. 
Please let me know what you think or what you did for this?

 Thanks.
