RE: photo imbedded in signature or profile
The image on the left is your "avatar". It represents you. It could be a photo of you, your boat or whatever. To accomplish this click on "User Details" in the bar above. Then click on "Avatar" on the top left of the new window. Then select "upload an avatar" (the center selection in the middle of the page). Then you will find and empty dialog box near the bottom of the page. Select the "browse" button. This will access your hard drive, where you will then locate and select a photo from your library. Then hit the "upload" button next to the browse button. It will take a while to load. When it is loaded, you will need to highlight it and then select the "upload avatar" button just beneath the photo. That's it.
