I had hard time learning it to enlarge thumbnail images. Finally, I got it right and it's working. Here is the complete code for anyone interested for all dp members: Just copy & paste and make small changes to the names of your images.jpg whatever you have. First the large images & then the thumbnail ones. You can add any number of images. No limit. Good luck! <head> <SCRIPT language=Javascript> function openWin(page,name,width,height) { winOpts = 'toolbar=0,width=' + width + ',height='+ height +',directories=0,status=1,scrollbars=0,resize=0,menubar=0,location=0,copyhistory=0' if (navigator.userAgent.indexOf("Mac") >= 0) { var W = open(page,name,winOpts) open(page,name,winOpts) } else { var W = open(page,name,winOpts) } W.creator = self; } </SCRIPT> </head> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> <table width="90%" border="0" align="left" cellpadding="0" cellspacing="0"> <tr> <td><p align="center"><a href="javascriptpenWin('images/style_large_one.JPG','pop3',720,540);"><img src="../images/style_large_T1.JPG" border="0"><br> </a> </td> </tr> <tr> <td><p align="right"><a href="javascriptpenWin('images/style_mid_one.JPG','pop3',720,540);"><img src="../images/style_mid_T1.JPG" border="0"></a> </td> </tr> <tr> <td><p align="center"><a href="javascriptpenWin('images/style_mid_two.JPG','pop3',720,540);"><img src="../images/style_mid_T2.JPG" border="0"></p></a> </tr> <tr> <td><p align="center"><a href="javascriptpenWin('images/style_mid_five.JPG','pop3',720,540);"><img src="../images/style_mid_T5.JPG" border="0"></a> </td> </tr> </table>
