JavaScript Image Magnifier: "
This is a fun one. A small JavaScript image magnifier has been released.
With a big of JavaScript, you can add magnification to any images on your page.
You can add:
<script type='text/javascript' src='http://valid.tjp.hu/zoom/tjpzoom.js'>
</script>
and:
<div style='float:left'
onmouseover='zoom_on(event,300,239,'image.jpg');'
onmousemove='zoom_move(event);'
onmouseout='zoom_off();'>
<img src='image.jpg'/>
</div>
You can also have a high-res image for the zoom piece, and use a low-res as the main image on the site.
Could be useful for some Where's Waldo? Product Zoom? and adult sites? ;)
