I guess this means you have no idea about how databases work. The language used by databases is called SQL. You can call SQL from VB via what's called a stored procedure ( essentially a 'program' that you call by name in your DB ), or by straight SQL code. You would write code like

select image from images where id = @id

and then either use a paramaterised query or a stored proc to insert the value for id.

Then your question was vague to the point of being meaningless. OK, then you want to write a http handler or just an ASPX that takes the id on the URL, then returns the bytes of the image with the correct mime type. Then you make the source URL of your image control point to that page, such as loadimage.aspx?id=57, and the browser will send the request and return the image. This is widely documented on the web, if you try to search, you'll find tons of examples.
