    That was just an accident when we edited the "real" URL to create the sample
    we sent you. The actual code does not have any embedded spaces.

    This is not the true. Putting the relative url inside single quotes made
    lookup of relative url's work. For example:

    <fo:external-graphic width="1.75in" src="url('images/logo.jpg')"/>

    works fine and gets the graphic relative to the current Cocoon context. But
    an absolute URL still doesn't work.

    The actual width of the image is the same as the width property, so this is
    definitely not the issue.

    And your comment on absolute URL's of the form:

     <fo:external-graphic width="1.75in"

    That doesn't make any sense whatsoever. localhost is a perfectly valid host
    name that should be resolved to XEP should not care what machine
    the image is located on, since Java's handling of URL's makes this totally
    transparent, unless XEP is doing something very strange internally. And if
    that is the case, I consider this a bug in XEP.

    Note that entering the absolute URL exactly as shown above in a browser on
    the local machine returns the image just fine.

    Could you please look into the XEP code that is handling the external-graphic
    src="url()" attribute? It is my belief that there is something in your code
    that shouldn't be there that is causing this.
