My approach to externalizing image paths was to extend
org.apache.struts.taglib.html.ImgTag and use a custom tag to define image
URL's using the existing pieces ImgTag provides. Overriding src() is used
to look up the look up the image URL base path from a properties file.
I've similarly created a custom tag that outputs the image URL as a string,
so that it can be used in JavaScript or in other ways if necessary, and it
relies on a common utility method to retrieve the image URL path that is
shared with the ImgTag subclassed tag.
