I tried this and it did not work.

With your help I was able see that dbparam.dsl and the DSSSL in the Cogent 
reference both contain admon graphics path controls.  Closer inspection of 
the Cogent file has a comment stating results similar to mine regarding the 
admon-graphic-default-extension control.

When I changed "warning.gif" to "warning.png" in dbparam.dsl, the warning.png 
icon was used.

I guess I'll substitute "png" for "gif" in dbparam.dsl unless I'm this is 
wrong. (I'm doing this in the html version.)

Here is the relevent section from the Cogent reference at
http://developers.cogentrts.com/cogent/prepdoc/pd-customizingthedssslstylesheets.html:

;; This overrides the default .gif extension for print admontions.
(define ($admon-graphic$ #!optional (nd (current-node)))
  (cond ((equal? (gi nd) (normalize "tip"))
 (string-append %admon-graphics-path% "tip.png"))
((equal? (gi nd) (normalize "note"))
 (string-append %admon-graphics-path% "note.png"))
((equal? (gi nd) (normalize "important"))
 (string-append %admon-graphics-path% "important.png"))
((equal? (gi nd) (normalize "caution"))
 (string-append %admon-graphics-path% "caution.png"))
((equal? (gi nd) (normalize "warning"))
 (string-append %admon-graphics-path% "warning.png"))
(else (error (string-append (gi nd) " is not an admonition.")))))

;; Identify the default extension for admonition graphics. This allows

(define admon-graphic-default-extension ".png")

Since I am coming to this list for free help then I want to make sure I am 
using tools that are current.  I don't work with DocBook much so I'm still 
trying to choose which processing technology to spend time learning.  
Openjade seems to work fine so I'll stick with it until I find a good reason 
to change.  Output styling is not a top priority for me now.

Thanks for your help.
