\will be escaped. So use\\instead of\. I think this will solve your problem.
Thank you but it doesn't work too.

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.

Thank you Guffa, Here is my code: <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %> // 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"; /***** DO NOT EDIT BELOW *****/ 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 -->

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. // <!CDATA[ function Button1_onclick() { document.getElementById("img1").src="C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Water lilies.jpg" } // ]]>
Thank you, Eric H.
