Hi,
Two possible solutions:
1. Use the Auctiva tag [IMGS_PAIRED] for all the images. It's on that hidden list on the template builder.
2. Build a table of 10 Rows x 2 Columns, and here's that starter at the practice board. I used cellspacing=10 and left or right aligned the images so they'd pair at the center with equal distance.

Depending on the image sizes, you can VALIGN= all the TDs with TOP MIDDLE or BOTTOM.
