A problem with images. html vs fo

I've a piece of xml which refers to a web page.
<link
xlink:href="http://www.kbgs.com/Ingrow%20Infants%201951.jpg">This</link>

The html is fine.

XEP produces

This
[http://www.kbgs.com/Ingrow%20Infants%201951.jpg] shows

Is this an XEP feature? Any reason the image shouldn't be
pulled from the web?

Or should I pull the file locally and refer to it from there?

Any advice please.

Using 1.75 (actually snapshot :-)
