I asked this before, but got no answers. 
Is it possible to rotate an image before it is placed inside a frame? 

Imagine a portrait page. 
On this, I place 4 portrait frames, whose proportions are the same as the images I want to place in them. 

But the images on my hard drive are in landscape format (and I don't want to rotate them on the hard drive). 

If I place a landscape Image in a portrait frame, and Fit Proportionaly and Center it, it will leave a white band above and bellow the image in the frame. 

What I would like, is a script which sees the image is wider than tall (i.e landscape), compare it to the frame it sopposed to go in (in this case taller than wide), and if this is portrait, rotate the image 90 derees right, before it places the image into the frame. 

After this, apply the Fit Proportional and Center Image in frame commands. 

How can I do this? 

Thanks, 

Bill
