Two images landing on same slide from different directions

[dsurls1465]

Hello,

In a previous Photostage project I had a slide where two different images slid onto the slide during the opening transition, one from the left and one from right, then each landing on the opposite sides of the screen for the duration.  Unfortunately I no longer have the project file, even though I still have the final executable video, so I cannot see how I did it.  I'd like to do it again, but do not see how to do it, presumably using Image Overlay.

Can anyone help?

Thanks!!
