newbie-can not render svg image within html document?

Hi.

I have several graphs that I have in an html document. 

Example of one:

 

<img

src=""http://ldi.rhoderunner.com/hra/servlet/chart?val=x&title=Health+Score&showLegend=true&series=November+1999&chartValues=1&chartValues=41&chartValues=1&chartValues=1&chartValues=50&chartValues=24&chartValues=1&series=November+1999&chartValues=1&chartValues=41&chartValues=1&chartValues=1&chartValues=50&chartValues=24&chartValues=1&series=April+2001&chartValues=1&chartValues=26&chartValues=1&chartValues=1&chartValues=25&chartValues=15&chartValues=1&series=April+2001&chartValues=1&chartValues=26&chartValues=1&chartValues=1&chartValues=25&chartValues=15&chartValues=1&categories=Cancer&categories=Heart+Disease&categories=Emphysema&categories=Cirrhosis&categories=Arthritis&categories=Overall&categories=Self-assessed+Health">http://ldi.rhoderunner.com/hra/servlet/chart?val=x&title=Health+Score&showLegend=true&series=November+1999&chartValues=1&chartValues=41&chartValues=1&chartValues=1&chartValues=50&chartValues=24&chartValues=1&series=November+1999&chartValues=1&chartValues=41&chartValues=1&chartValues=1&chartValues=50&chartValues=24&chartValues=1&series=April+2001&chartValues=1&chartValues=26&chartValues=1&chartValues=1&chartValues=25&chartValues=15&chartValues=1&series=April+2001&chartValues=1&chartValues=26&chartValues=1&chartValues=1&chartValues=25&chartValues=15&chartValues=1&categories=Cancer&categories=Heart+Disease&categories=Emphysema&categories=Cirrhosis&categories=Arthritis&categories=Overall&categories=Self-assessed+Health"/>

 

If I go to the directly to the URL above, (  http://ldi.rhoderunner.com/hra/servlet/chart?val=x&title=Health+Score&showLegend=true&series=November+1999&chartValues=1&chartValues=41&chartValues=1&chartValues=1&chartValues=50&chartValues=24&chartValues=1&series=November+1999&chartValues=1&chartValues=41&chartValues=1&chartValues=1&chartValues=50&chartValues=24&chartValues=1&series=April+2001&chartValues=1&chartValues=26&chartValues=1&chartValues=1&chartValues=25&chartValues=15&chartValues=1&series=April+2001&chartValues=1&chartValues=26&chartValues=1&chartValues=1&chartValues=25&chartValues=15&chartValues=1&categories=Cancer&categories=Heart+Disease&categories=Emphysema&categories=Cirrhosis&categories=Arthritis&categories=Overall&categories=Self-assessed+Health  ) it works, but if the url is part of an html document, it will not (e.g. <img src=""/>

 

Is there something special about svg that I need to do differerently than jpeg?  I am outputting a mime type of image/svg+xml

 

Thanks!
