Ho usato questo codice per ridimensionare un'immagine (sono descritti tutti gli step!), è l'unico che ho trovato che linkasse a una immagine e non a una pagina html, mi funziona benissimo con windows ma con mcintosh non ne vuole sapere, vi prego aiutatemi!!!anche se avete codici alternativi (che linkano immagini però).. GRAZIE

Script: Auto-Sizing Image Popup Window
Functions: Use this script to launch a popup window that
automatically loads an image and resizes itself
to fit neatly around that image. The script also
places a title you set in the titlebar of the
popup window. Any number of images can be launched
from a single instance of the script.
Browsers: NS6-7 & IE4 and later
[Degrades functionally in NS4]

STEP 1.
Inserting the JavaScript <script> In Your Page
Insert the following script in the <head>...</head> part
of your page. Take special care not to break any of the lines;
they must be exactly as shown.
Set the variables as per the instructions in the script.
<script>
// Script Source: CodeLifter.com
// Copyright 2003
// Do not remove this notice.
// SETUPS:
// ===============================
// Set the horizontal and vertical position for the popup
PositionX = 100;
PositionY = 100;
// Set these value approximately 20 pixels greater than the
// size of the largest image to be used (needed for Netscape)
defaultWidth = 500;
defaultHeight = 500;
// Set autoclose true to have the window close automatically
// Set autoclose false to allow multiple popup windows
var AutoClose = true;
// Do not edit below this line...
// ================================
if (parseInt(navigator.appVersion.charAt(0))>=4){
var isNN=(navigator.appName=="Netscape")?1:0;
var isIE=(navigator.appName.indexOf("Microsoft")!=-1)?1:0;}
var optNN='scrollbars=no,width='+defaultWidth+',height ='+defaultHeight+',left='+PositionX+',top='+Positi onY;
var optIE='scrollbars=no,width=150,height=100,left='+P ositionX+',top='+PositionY;
function popImage(imageURL,imageTitle){
if (isNN){imgWin=window.open('about:blank','',optNN); }
if (isIE){imgWin=window.open('about:blank','',optIE); }
with (imgWin.document){
writeln('<html><head><title>Loading...</title><style>body{margin:0px;}</style>');writeln('<sc'+'ript>');
writeln('var isNN,isIE;');writeln('if (parseInt(navigator.appVersion.charAt(0))>=4){');
writeln('isNN=(navigator.appName=="Netscape")?1:0; ');writeln('isIE=(navigator.appName.indexOf("Micro soft")!=-1)?1:0;}');
writeln('function reSizeToImage(){');writeln('if (isIE){');writeln('window.resizeTo(100,100);');
writeln('width=100-(document.body.clientWidth-document.images[0].width);');
writeln('height=100-(document.body.clientHeight-document.images[0].height);');
writeln('window.resizeTo(width,height);}');writeln ('if (isNN){');
writeln('window.innerWidth=document.images["George"].width;');writeln('window.innerHeight=document.ima ges["George"].height;}}');
writeln('function doTitle(){document.title="'+imageTitle+'";}');writ eln('</sc'+'ript>');
if (!AutoClose) writeln('</head><body bgcolor=000000 scroll="no" onload="reSizeToImage();doTitle();self.focus()">')
else writeln('</head><body bgcolor=000000 scroll="no" onload="reSizeToImage();doTitle();self.focus()" onblur="self.close()">');
writeln('[img]+imageURL+[/img]</body></html>');
close();
}}
</script>
================================================== ============
STEP 2.
Calling the Image Popup from Links in Your Page
This is the form of the function:
popImage("url_of_image","title_of_image")
Use the relative or absolute path of the image where we show
url_of_image. This is the url of the image you wish to show
in the auto-sizing popup window.
Use any text you wish where we show title_of_image. This is
the title that will appear in the titlebar of the popup. (Note:
do not use single- or double-quotes within a title.)
Caution: Be careful to place both values within quotes.
See the samples below.
