Dynamic images in ASP & SQL

Hi,
I’m working on a SQL-database driven web application in which I want to include dynamic images. I’m developing in Macromedia Dreamweaver UltraDev 4. My pages are connected to MS SQL Server 7.0
My question is in which format to put data in SQL Server so that I can retrieve this in ASP-pages.
Images are in JPG & GIF format.
Thanks very much,
CONIX Wim
