Well, as far as I know it is.  I replied to the original sender, but I can't
remember if I posted it or not. So here goes.

Macintosh technical note #253 documents how to include SICNs or reduced
size regular ICONs next to menu items, like Multifinder does.  This 
facility came about when Multifinder was being created, so it isn't 
documented in Inside Mac.  The first thing you need to do is place a 
value of $1D in the cmdChar field of menuItem for a reduced ICON, or a 
value of $1E for a SICN.  You then place the resource ID of the 
appropriate ICON or SICN, minus 256, in the itemIcon field.  Note that
this means that the resource ID of your ICON or SICN must be 257 or 
greater.  Also, since the cmdChar field is used up, you can't have 
keyboard equivalents for these menu items.  Oh well.

   In code:
    SetItemCmd(theMenu,item,$1D)    { reduced icon (reduced ICON) }
    SetItemIcon(theMenu,item,icon)

or

    SetItemCmd(theMenu,item,$1E)    { small icon (SICN) }
    SetItemIcon(theMenu,item,icon)

That's it.  It works for a normal menu, so there's no reason why it shouldn't
work for a popup.
