I'm not sure I understand the question, but my preference is for writing 100% code, no designers. I'd prefer to have a framework within which my code specifies the stored procs to call, the parameters, and return the result.

Please help here is the code
Thank you.
// width to resize large images to
var maxWidth=100;
// height to resize large images to
var maxHeight=100;
// valid file types
var fileTypes=["bmp","gif","png","jpg","jpeg"];
// the id of the preview image tag
var outImage="previewField";
// what to display when the image is not valid
var defaultPic="box_icons.jpg";
function preview(what)
{
var source=what.value;
var ext=source.substring(source.lastIndexOf(".")+1,source.length).toLowerCase();
for (var i=0; i<fileTypes.length; i++) if (fileTypes[i]==ext) break;
globalPic=new Image();
if (i<fileTypes.length)
globalPic.src=source;
else
{
globalPic.src=defaultPic;
alert("THAT IS NOT A VALID IMAGE\nPlease load an image with an extention of one of the following:\n\n"+fileTypes.join(", "));
}
setTimeout("applyChanges()",200);
}
var globalPic;
function applyChanges()
{
var field=document.getElementById(outImage);
var x=parseInt(globalPic.width);
var y=parseInt(globalPic.height);
if (x>maxWidth)
{
y*=maxWidth/x;
x=maxWidth;
}
if (y>maxHeight)
{
x*=maxHeight/y;
y=maxHeight;
}
field.style.display=(x<1 || y<1)?"none":"";
field.src=globalPic.src;
field.width=x;
field.height=y;
}
// End -->
Test it by locating a valid file on your hard drive:

Unable to find problem in your code since it is too big. I did this by simply specifying local image path to image tag src using javascript. Try that method.

Hello,
I simplify the problem, please see the following code:
// <!CDATA[
function Button1_onclick() {
document.getElementById("img1").src="C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Water lilies.jpg"
}
// ]]>
Thank you much

In javascript \ will be escaped. So use \\ instead of \. I think this will solve your problem.

Thank you for your help,
You can copy the code from my first post

As you didn't use the "Ignore HTML" option when you posted the code, he can't use it. There are several parts of the code that doesn't show up in the message.

As I wrote upstair, I simplify the problem to a short code. Can you try to help me on this code. I think it will help me to the big one too.
The problem is that I do not see the picture.
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<script language="javascript" type="text/javascript">
// <!CDATA[
function Button1_onclick() {
document.getElementById("img1").src="C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Water lilies.jpg"
}
// ]]>
</script>
</head>
<body>
<form id="form1" runat="server">
<img src="" style="width: 96px; height: 96px" id="img1" />
<input id="Button1" type="button" value="button" önclick="return Button1_onclick()" />
</form>
</body>
</html>
Thank you,
Eric H.

System.NullReferenceException was unhandled by user code
Message="Object reference not set to an instance of an object."
