We have posted an update to OrbitZoom the free zoom pan image viewer.
1. We removed the logo that appeared at the bottom when rolled over.
2. We added functionality to let you hide (then show) the cursor with the H key.
Also we noticed that when you pass a picture directly to the swf file in a URL or the command line URL then IE thinks it is a jpg for instance and not a swf. So please add an & at the end of the URL to remedy this.
We are further considering a zoom out mode beyond the double click. We will see.
