Yes, absolutely! You can even preview your slideshow without an active internet connection. Photo Album Pro is entirely self-contained and does not rely on any external Javascript libraries. As a result, you can preview your slideshow:
- Behind a corporate firewall
- On a train, plane or ferry
- From a CD, DVD or flash drive
- Any other location without an internet connection
Your RapidWeaver theme may still require an internet connection though, in order for page elements like drop-down menus and ExtraContent to work. However there are some themes available which (like Photo Album Pro) can functionally perfectly fine offline without an internet connection.
Please note that some of the special animation effects may not work correctly in RapidWeaver preview. The fall-back animation effects may be used instead.
