I don't understand this. You declare H and V using a clever method, but then 
don't use those variables at all...

I'd simply say:

#local W = image_width/sqrt(image_height*image_width);
#local H = image_height/sqrt(image_height*image_width);

// in the camera definition use:
right    x*W
up y*H // or z*H if Z is up
