Is this kind of doing what you are looking for?
Group some radiobuttons with tool names
!!! be careful the tool names are case sensitive
Set the script of a field under image "xxx" to this:

on mousemove
   if the mouseloc is within the rect of img "xxx"  then
     if the mouse is not down then
       put the hilitedbuttonname of group "tools" into a
       choose a tool
       checkformousewithin
     end if
   end if
end mousemove

on checkformousewithin
   if  the mouseloc is within the rect of img "xxx" or the mouse is down 
then
     send "checkformousewithin" to me in 100 millisecs
   else
     choose browse tool
     set the checking of me to false
   end if
end checkformousewithin

mouseEnter and mouseLeave messages are not always trustworthy with
superposed controls and can screw up a handler depending on it.
