display an image from a sql database

Please help me:
I'm storing an image (image.jpeg) in an Image field in SQL server, and has put that field in the report, but it comes blank!

Do I have to use some other special field to display this or just put this database field as it is.

I've one more problem, When I try to export this report to a pdf
file, it gives an error
"Error in File<PathName/Fle.rpt> Error detected by Export DLL"

Ever come across this?...i'm going nuts..
Any help is appreciated, thanks

Tom.

what 'type' of field does CR think it is? (right click on the field on the report, and at the top of the pop menu it will say)

BLOB field
