Example:
var imageObj = document.getElementById("imagePreview" + curcontentindex)
Reflection.add(imageObj, { opacity: 2 / 10 });

I think that attaching the event using window.onload is not the best approach.
How about using window.addEventListener?
I've changed your script to the following:

Instead of:

var previousOnload = window.onload;
window.onload = function() { if (previousOnload) previousOnload(); addReflections(); }

I put:

if (window.addEventListener) { // DOM method for binding an event
window.addEventListener("load", addReflections, false);
} else if (window.attachEvent) { // IE exclusive method for binding an event
window.attachEvent("onload", addReflections);
} else { // Support older browsers
var previousOnload = window.onload;
window.onload = function() { if (previousOnload) previousOnload(); addReflections(); }
}

Absolutely loving the script.

We are using for our new corporate website. One thing i improved upon was the ability to set a spacing between the image and the reflection, added a rspacing option that takes a value in pixels and puts a gap in, i personally think it improves the look of the reflection with a small gap.!.

If you like i can send you the changed version, might be nice to let other people use this feature.

Thanks, Chris.

But if i use the reflected image as a link, the target function doesn’t work. i want to open a page in a iframe is there any way to do this with a reflected image? I’ve something like this:

thanks!
