thank you! I'm so grateful for someone willing to help, but I'm terrified I'm going to frustrate you with my limited knowledge.
I edited the .htaaces file to reflect the path exactly as you said, and I went back in and opened the file (using fetch) after I uploaded it to verify it saved correctly. it did. but now, i can't get into my zen admin or setup. it just takes me back to my blog.
if I type in the exact path, I still get the 500 internal server error.

I tried changing these back to their original settings but the same thing happened. so I changed them back because this is how they were when you originally looked at my problem. do you think this is wehre the error is?
// define('WEBPATH', '/wp-content/plugins/zenphoto/albums');
// define('SERVERPATH', 'http://www.haute.cc/hauteblog/wp-content/plugins/zenphoto/');
