Yes, I did. The first time I had the tar.gz version and it would create a folder named "1.0b" and it contained 8 items.
Then I downloaded the .zip version, and when unpacked it created a folder named "zenphoto-1" which had the same 8 files/folders. Same results with both. For the sake of disparity, I downloaded the files again with Firefox instead of Safari, and I still get the same thing.
I have a feeling the problem lies in my build of php5 but I only say that because I was able to get zenphoto to work just fine on my Mac at work and as near as I can tell the only difference is that my Mac at work has php 4.3.11 and my problem Mac has 5.1.2. I'm just not smrt enough to know how to trouble shoot this. And like I said, both wordpress and gallery are running just fine on this Mac.
