how to retrieve image from database??HELP!!!

I need help. How to retrieve image from database and display in on the web form???
Like for e.g; i want the image to change every time when i put the different title of the book. So how can i achieve the image so that it will change everytime when i put the different title of the book??

the main idea is to open a datareader with the database.

read the image and write it to the page output through the response.write method.

you should use a stringbuilder beacuse there will be a lot of text manipulation.

good luck
