问题
First off, just want to thank the author for making this great bit of code available for free, and the community for helping java-illiterate folks such as myself.
Anywho, here is my issue: When I click a thumbnail to enlarge it, it enlarges just fine. However, when it's enlarged, the only way I can shrink it is by placing the cursor on the very thin ~1px border. I do not get the magnifying glass shrink cursor when over the image itself. If you wish to view the problem, the code is live at http://www.coloradocanopyclub.com/photos.html.
*EDIT TO ADD* This issue seems to be affecting the first photo ONLY. (tallison.JPG)
Thanks for any help!

The universal selector at the top of your style.css file causes this problem:* {margin:0px;padding:0px;top:0px;left: 0}
It’s ok to set margin and padding to 0 for all elements, but the problem starts when you sets top/left position for all relative/absolute positioned elements 0.
You’ve probably noticed the Highslide full-expand button. This button is placed in an overlay on top of the image. Standard position for the full-expand button is bottom right corner: http://screencast.com/t/WPP4iwwCI9dq Your universal selector moves it to upper left corner: http://screencast.com/t/maXl9rzveH When the button is moved like this with CSS, it will result in an overlay that covers the entire image – colored red in this screenshot: http://screencast.com/t/6pdDnxaMRQ - which makes it impossible to close the image.
You need to change your universal selector to this:* {margin:0px;padding:0px;}
And add top:0px;left:0px; only to the selectors where you need it, which are (as far as I can see) #navlist li a span and #content
