restore image file from database

[manared]

Hi, I'm using vb.net with asp.net and SQL. I have a binary file stored in an image field in my database. I have a page that shows a gridview with all the files stored for that particular order. When one of the files is clicked on in the gridview, I want to go to the database, grab that file, and have the user see it or have the option to save it to his/her own computer. How can I do this? I have a web based application. Thank you in advance!!!
