RobbieB1953 on "Image path for footer"

I want to add an image to my footer:
http://bit.ly/1fkapvd
but I'm confused as to the path for the image.
Forums refer to a path like this:
'<img src="http://mydomain.com/myimagefolder/image.format" alt="Image Description">'`

or
'<img src="http://mydomain.com/uploads/image.format" alt="Image Description">'

but the images for the site reside in wp-content/uploads/2013/09/image name here

When I know the right path then I can add this to ? line of the footer.php?

Thanks!
