Hello all,
I have a javascript that when you move your mouse over a thumbnail, a popup with a bigger photo appears. Now when a photo is bigger than half the screensize (eg. screenwidth = 1024 and photo is 600) the photo doesn't show completely anymore.
Question: Is it possible to add something to the script so when the photo doesn't show completely anymore, the popup resizes to a smaller size that fits in the screen?
Here's the code
Hope someone can help meCode:<html> <head> <!--SHOW IN SCREEN 1024x768--> <script language="JavaScript"><!-- self.moveTo(0,0) self.resizeTo('1024','768') //--></script> <script language="javascript" type="text/javascript"> <!-- /* Image w/ description tooltip- By Dynamic Web Coding (www.dyn-web.com) Copyright 2002 by Sharon Paine Visit http://www.dynamicdrive.com for this script */ /* IMPORTANT: Put script after tooltip div or put tooltip div just before </BODY>. */ var dom = (document.getElementById) ?
