General Support: Broken path to large image

I just set up Plogger and everything seems to be working, except when I click the image to to get large version it totally mangles the path.

Here's the image path:
http://www.murphyhomesboulder.com/webgallery.php?level=picture&id=4

Here's the path to the script:
http://www.murphyhomesboulder.com/cgi-bin/ploggerb3/

And here's the mangled path it is generating for the large version:
http://www.murphyhomesboulder.com/webgallery.phpimages/gallery/test_album/boysbath.jpg

So rather than linking back to within the Plogger directory, it's linking back to the HTML file itself. Any ideas?

That fixed it. Thanks!
