Hert, how many images can you put in idImager.
idImager is limited by the size of the database. The personal edition uses MSAccess database which is limited at 2GB of size. The Professional Edition can work with SQLServer Express or SQLServer 2005. Express is limited at 4GB and 2005 is "unlimited".
FYI; idImager does not store thumbnails inside the database, prevening the database from flooding too fast.
