asp.net - IMG SRC tags and JavaScript

Question

Is it possible to call a JavaScript function from the IMG SRC tag to get an image url?

Like this:

<IMG SRC="GetImage()" />

<script language="javascript">
   function GetImage() {return "imageName/imagePath.jpg"}
</script>

This is using .NET 2.0.

Nope. It's not possible, at least not in all browsers. You can do something like this instead:

<img src="blank.png" id="image" alt="just nothing">
<script type="text/javascript">
    document.getElementById('image').src = "yourpicture.png";
</script>

Your favourite JavaScript framework will provide nicer ways :)
