I have a FotoPlayer Pro version. Now JAlbum has a Pro version. Do I need to pay for JAlbum Pro since I already have FotoPlayer Pro? I have shopping cart in FP. Do I need to pay for same feature in JAlbum?
jAlbum and FotoPlayer have no business relationship. If you want to use FotoPlayer for a commercial site, you must have a Pro license from FotoPlayer. If you want to use jAlbum for a commercial site, you must have a Pro license from jAlbum. The two have nothing to do with each other.
The Pro license for jAlbum doesn't relate to the shopping cart. It covers any use of jAlbum, with any skin, for commercial purposes.
