Updating User Profile List From UI using C# code

Hi,

I have created a web part through which I am giving option to user to update their Profile info.

This info will get reflected in User Profile List.

I am successfull in updating the list from UI using c# code.

I also want to give option to user to upload the picture from UI using the same web part.

Can u please guide me how to do that ?

How to use file uploader for that ?

Thanks in Advance
