Found the solution (after I posted of course). Random selection works fine. 
My loop code (copied from an example) is wrong for this application. Here 
is the corrected loop code:

[loop
           random=1
           search="
                   fi=products
                   st=db
                   sf=category
                   se=[item-field category]
                   ml=1000
                   tf=category
                   rf=code,image
           "]

<td align="center"><img src="items/[loop-param image]" width="150">
[/loop]

Aside from my loop search being incredibly wrong, I was using [item-field 
image] instead of [loop-param image]. A related message from Kevin Walsh 
gave me a clue on this.

Now I get a random image from each category to be used as a banner image 
(or whatever).

Perhaps this will help someone else down the line.
