Aligning images along a circular plane and then animating them into view. Any idea how?

Okay, so I am trying to align a series of logo images onto an oval plane and then animating the series so as if they are being rotated into view. Picture a globe and as it rotates a new image appears and it travels along the circular plane of the earth. My project is similar, except instead of a round earth, it's an oval circular plane. And there are 12 logos. As each rotates into view the frame freezes on the logo, then quickly spins to the next. Each logo will be evenly spaced and should be linked so they rotate together and along the same speed and plane.

So I am wondering is there anyway to create an oval object and attach these logo images to it's plane, rather than manually adjusting the the 3d position settings to create the even seperation and plane angle?

Any idea how to do this? Or if not, the easiest way to attach them to a curved circular plane evenly?


Thanks
