Tags questions

[Jack <ostroffjh sbcglobal net>]

First, is there any way (within the program) to remove the image/icon  
from ALL tags at once, instead of doing it one at a time?   Otherwise,  
can someone confirm it could be done by an appropriate sql update in  
the database.

Second, it seems in the main display, that if a tag does not have an  
icon, then the icon of it's parent is displayed under any photo with  
that tag.  However, if none of the parents, up to the root, have an  
icon, then no icon at all is displayed, so you can't quickly tell if a  
photo has any tags.  Is the easiest (and only?) way to deal with this  
to simply assign some icon to the top level tag?

Thanks.
