I have Image Handler 2 and jqlightbox installed and both are working perfectly.
I then installed jqzoom which worked, but the zoomed images are the same size as the large image shown in jqlightbox.
That being the case, it only makes sense to me to install either jqlightbox or jqzoom, not both of them.
If jqzoom could zoom on the original image loaded rather than the image handler large image, I could see the point in both of them. In fact, it would be fantastic!

This is my setup:

I load a product image which is 1500 x 1000 pixels.
I set image handler to display large images as 750 x 500 pixels as I think anything larger than this is too big for most screens to display.

When I click on the image, it is displayed in the lightbox at 750 x 500 pixels which is perfect.
When I roll over the image, jqzoom only zooms the image in to 750 x 500 pixels so it doesn't show any more detail than the lightbox does.

What I would like to be able to do is have jqzoom zoom in on the original 1500 x 1000 pixel image, thus showing the customer much more detail than the lightbox.

Is this possible?
