Hi Hermann,
The major thing that jumps out at me from your code snippet is that
early on you're referring to the photo element by _gel("photo"), then
later you use document.images["pic"]. Are these the same HTML element?
Minor(?) thing: your resizing tests won't work for any square photos
(H = W).
Could you post a link to the live gadget instead of a snippet? There's
lots that we can't tell from just looking at this (HTML, photo
dimensions, other JS) that could be influencing this. Plus it's vastly
easier to debug a real example.
