The image has to be visible when you initialize pinchzoom, or the JS code can’t find the container. It’s in the onchzoom docs.
I think what @Michael_Hill was getting at was to totally drop the pinchzoom.js and use the concepts in his link to perform the function.
Thanks Mike. I was looking for a CSS method, as the JS is way too slow on an image of any consequence. When I get a chance, I’ll try it out.
