The following image functions can be called with one or two parameters. If there
is only one parameter it is assumed that the image is loose in the /images/
directory and we are simply calling the function with the image short name. If
there are two parameters then we are passing the image name and the path off of
the /images/ directory that the image resides in.

Primarily for nav type image routines - otherwise the code can just be inline.
