I think the problem is the type file you're trying to upload. It works best with a jpg image. Your photo that's in your first post is a .php file. I don't think the software will "play well" with that type file.
Try saving the file in your first post by right clicking it, then "save as" to your desktop as a .jpg file.
Then go to "User CP", click on "Edit Profile Picture", then click on "choose picture" and then when the "upload window" opens, select that ",jpg" photo from your desktop. Then click on "save changes"...
Hopefully it will "magically appear"....
Hope this works for you....
