CS2 multiple layers aligned along a curve

Hi
I am trying to align multiple warped (curved) rectangles each on a separate layer along a single curved edge, so that the left hand edge of each layer lines up with the layer above it.

The curve starts and ends at the centre top and bottom of the A4 page and curves to the left hand side of the page, so I want each rectangle to appear 1 below the other, neatly aligned to the curve.

any suggestions welcome

thanks

Zoom in and align them carefully.

Of course, it would be easier to align all the undistorted images in a straight line and then distort them as one unit

Of course, how stupid, thanks so much for pointing out the obvious!! Sometimes I get so bogged down in the capabilities of Photoshop, that I over look the simple things.

thanks again
