You DON'T have to use intermediary file! The
simplest (and not the most optimal) way is to stream the image from servlet.
This is as simple as sending couple of headers to the browser and writing the
image data to the "out". Most good database
servers (DB2, Informix etc.) have plugins and optimizations for media
files. I'm not sure about SQL2000.
If they are just a
static images you can store them on disk temporarily as some people suggested,
but than again if they are static why are they in the database in the first
place? If you're manipulating them in any way you may need to stream them
directly from servlet.

hi,
The other way it is done is to create image on
the fly.
Though u may want to consider
performance in both the methods. Below is a jguru link to give u directions.
hope it helps

How would I go about implementing this, since
I have to use a intermediary file --
Will this intermediary file stay on the
server? If so, how will the clients access that file? I'm just
really up to my ears with this one...
thank you

Jagdeep,
The standard practice is to create an intermediary file and cache it
for a fixed period of time for performance reasons. With a
standard HTML page, this may be your only option. One of my
clients has implemented a large imaging application and this the
approach that they have taken.

Hello all... Seem to have put myself in a little
situation. I have a
database (SQL Server 2000) where my images are stored. What I
would like to do is to retrieve those images directly (no external
file) and view them in a html page. For the twist...this application is a web
application and those images need to be seen by all clients who access
that application. I have read about URL's , but that didn't seem
to work... All help
is greatly appreciated!!jags
