I am trying to display an image (byte array) using purely JavaScript.

How can I achieve this in ASP?

javacript and image data are two different thinks, meaning that you can display image with base64 data, but the javascript not needed - you only needed if you try to manipulate the page. What are you have up to now, and what actually try to gain here ? Do you have any javascript code to show us for what you try to do ? – Aristos Feb 27 '12 at 11:14

If you have the byte array first you convert it to Base64String and then you place it on an img tag like that (for png image)

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot">
