You can place the thumbnails directly in front of the main image by positioning them using a Fixed Layout: http://simpleviewer.net/simpleviewer/pr … html#fixed
However, it is not possible to have the thumbnails as part of the overlay (which fades in and out on mouse-over and mouse-out).
There are over 200 configurable options available with which you can customize a gallery: http://simpleviewer.net/simpleviewer/pr … tions.html
Using svBuilder-Pro's live preview will show you how the gallery looks as you change these options in the interface: http://simpleviewer.net/simpleviewer/pr … uilderpro/
The SimpleViewer Pro API is also available which allows SimpleViewer Pro users to control and interact with SimpleViewer-Pro and create custom User Interfaces.
