It looks like that in Firefox too, at least on Ubuntu.
This seems to be the culprit:
Code:
<img src="http://www.iolani.honolulu.hi.us/robotics/newweb/allimg/home/first_logo_1.jpg" height="90%" width="90%" align="center">
That would mean that it's taking up 90% of the page vertically and horizontally. Use pixel values ("100px" etc.) instead as it wouldn't change with window size/screen resolution.
