Jeg holder stadig fast i mit argument med at det ikke kan betale sig at gemme indholdet, men måske kan du bruge dette:
<script>
function imgPop(imgSrc){
var newWindow = window.open("","NewImage","toolbar=no");
newWindow.document.open();
newWindowHTML = "<html><head><style>body{margin:0;}</style>";
newWindowHTML += "<scr"+"ipt>function mouseClicked(e){self.close();}\n";
newWindowHTML += "function initPage(){var img = new Image();img.src=\""+imgSrc+"\";window.resizeTo(img.width+10,img.height+30);}\n";
newWindowHTML += "document.onmousedown=mouseClicked;\n";
newWindowHTML += "window.onload = initPage;";
newWindowHTML += "</scri"+"pt>\n";
newWindowHTML += "</head>";
newWindowHTML += "<body>";
newWindowHTML += "<img src='"+imgSrc+"' id='img1' name='img1'>";
newWindowHTML += "</body></html>";
newWindow.document.write(newWindowHTML);
newWindow.document.close();
}
</script>
<img src="1.jpg" onClick="imgPop('1.jpg')">
