Problems in Report Presentation

Hello:
We are running SQL Server 2000 RS. We are just starting to deploy reports
and we are running into a strange problem.
We have given users access to their reports via various Windows security
groups. When an Sysadmin runs a report, it's runs fine and displays
everything in a timely fashion.
When a regular user runs a report, there is a significant delay while the
Report is Being Generated icon spins. Finally, the report displays but some
graphics are not displayed and are replaced by a box with a red X.
This behavior is consistent on any user who is not a sysadmin.
Any suggestions on how to correct this problem would be appreciated.
ThanksBrennan,
Do the images exist on a location where the group to which the user's
belong does not have permission?
I bet if you set the permission on the image to 'Everyone'/Anonymous
you'll get the images in the report.
