PostcardViewer, similar to AutoViewer (see WRD post) which is created by the same company, is a free Flash image gallery application with a very nice presentation.

The interface is just like a set of postcards shuffled onto a surface & this is supported with the effects.

This Flash gallery can controlled via mouse & keyboard. And it displays image captions (including URLs).

Besides this free version, pro version offers more customization and no backlink.

Requirements: Flash 8+
