dynamic dataset as source for crystal reports

Question

Hey guys


i'm trying to create crystal report with dynamic picture. I followed this: http://aspalliance.com/1097_Importing_Dynamic_Images_to_the_Crystal_Report_without_Database_Overhead_using_Visual_Studio_2005.all

Im getting images from url saving to stream then to disk then saving to dataset/datatable/byte[] as said in this "tutorial". And it works at least i can get image from it without a problem. The problem is during runtime i get message :

The report you requested requires further information.
Followed by few input controls for defining servername, database name, username, password.


I don't get it, why does it need connection info if there's no database connection, only a dataset "filled" with one byte[]field during run time.


Any help will be great

Thanks
