Pros:

-Fully-customizable web pages, lots of features and options.

Cons:

- The image order window has to be the absolute worst UI element I have ever seen, it's a deal-breaker for me. Chasing one file at a time up and down a linear list one click at a time, argh. Try moving 40 or 50 images around with this...

- Requires all source images to be in one directory, you can't drag and drop (or otherwise add images) from various places.

- Crashes every time I quit the program (OS 10.4.2)
