Zoom doesn't work

Hi,
First of all, congratulations for your work… I love this plugin.

But I have a problem… I use it in one of my stores, but I doens’t zoom at all.. it just show a thumbnail of the image.
I tried changing settings, tried to regenerate thumbails, nut nothing seems to work.

I’d really like some help.

Thanks
