Hi again,
Database support is included in qRules but assumes Qdabra's DBXL Web Service exists. Here's another link of an XTP we provide for people that use qRules to upload images to SharePoint or DBXL: http://www.qdabra.com/en/products/QdImagePicker.aspx
We could easily add HTTP file system support for you if you're interested. How about if you purchase qRules 2.1, we'll add the HTTP file system support to qRules v2.2? We hope to release v2.2 at end of May or early June and you could be our first beta tester.
Interested?
