You could simply create dynamic widgets on each page, load up their images, and then have them do something like:

assuming variable with widget is userFirm1.

userFirm1.onPress = function()
{
// when this button is pressed, it executes the real firm1.
// note that this approach will not allow press and hold (repeating ir) functionality.
GUI.widget('PS_FIRM1').scheduleActions();
}
