Sizing Vert & Horz images

Is there a way in actions or scrip to size a folder of different size horizontal and vertical images at the same time so that the longer edge ( h or V ) is equal - ie - horiz long side 2", shortside whatever on Horizontal - Vert long side 2", shortside whatever on vertical ? at present I am separating H & V and using two different actions .

I'm sure it could be scripted, but I have NO IDEA how.
