How to import programmatically an APEX images file using workspace images option and CSS files to APEX?

Question

Oracle db 11gR2
Oracle APEX 4.2.1
Linux RHEL 6.3
I am importing a images file programmatically into APEX.  And also a CSS file.
I want to add an images file to my APEX instance but I want to choose the option -- workspace images --.  How does one do that programmatically via the APEX API e.g.?
I don't want the images tied to an application within APEX.
Does one do the same thing for CSS files that are imported to APEX?
thx.

This is interesting and helpful,  I use the following code to import my APEX database application and run it via SQL*Plus and it works fine for database applications -- what do I need to change/add/modify in order to load the images and CSS files?  NOTE: I want the images to be -- Workspace images -- not tied to any application.  Also, I need to handle the situation where the images and CSS data already exist in the APEX environment as well as when they are not there (i.e. initial install).  Usually it is a case where it is an upgrade so the data already exists in the APEX app and just needs to be updated.
