If you are getting the dreaded javascript pageY error, open your includes/templates/YOUR_TEMPLATE/jscript folder and make the following tiny change to the jscript_imagehover.js

Very near line 124 you should see:
ycoord += event.clientY - Math.max(0,(0 + zoomimg_h + (5 * padding) + event.pageY - docheight - truebody().scrollTop));

it should be:

ycoord += event.clientY - Math.max(0,(0 + zoomimg_h + (5 * padding) + event.clientY - docheight - truebody().scrollTop));

The links in this thread to the support no longer work and the ones with instructions aren't very clear. Hopefully anyone looking for the fix will find it here.

Blessings,
