@Mark_Wonsil’s technique is the most portable. The images are in the RDL, and you don’t have to worry about them being the same size, cropping, stretch, etc…
Using referenced image files would allow you to change the image without having to edit the RDL.
But if anyone else knows how to pass an image from the DB (the actual image contents, not a reference to the source file) to a report, I’d love to learn about that. [ bat signal to @Carson ]
