How to show/hide thumbnails stack which is created using "buildthumbs();"?

Best way is to open them at start and then just show/hide them like this.

This way you get instant opening on the iPad.
If you close them completely as the default way it may take up to 5 sec to open them again on the iPad iPhone.
