How do I get an image from DB into an asp.net control?
Below is my code that works the way it is written... it pulls the blob image out of the database and displays it on a webpage. But what if I want it to display in a control on that webpage? Right now I have 2 aspx pages.
The first one just gives the second on the ID.
<a href="WebForm1.aspx?ID=70"
The second one displays the image. But I need to put other information on this page so I need the image to go into a placeholder. I just put an <img> tag on this page. How do I get the output from the below code to go into that img tag?

You have to put one literal control for getting image, and into coding side, you have to write like this.
Get the data into DataReader
While Reader.Read
literal1.Text = "<img src='../Images/' " & Reader.Item("ImageFiledNam
End While
