Hi, thanks for asking a question. Panzoom uses CSS transformation matrices and transitions that are not supported in IE8. However, if you are seeking panning and zooming capabilities for an image element, I would direct towards some excellent plugins:Panning
Zooming is a different story. No one has really gotten this to work correctly in IE8. The best solution I’ve seen has been to to increase the width and height of an image, which doesn’t really require a plugin. That said, you may be interested in jQuery Zoom, which has its own take on the UX of zooming.
