Here you can download the same template with 10 thumbnails:download/file.php?id=365
(also added this to the template section's post)
What you need to do when adding the thumbnails, and for them to stay in the right position, is to use the alignment component in the hotspots tab.
First, click one of the other thumbnails to see what the settings for those are. Static tickbox is ticked, and the alignment components align to center upper position (left alignment component is clicked in lower center position, while the right component is clicked in the top center position.
Then you need to move the images to the right positions, which can be done with the numeric steppers in the hotspots tab, or with the onscreen tool.
Hope this helps you to get further.
