Currently, if a user enters an address to a gallery and mistypes, or if that gallery has been renamed, the user gets this error "Zenphoto error: Album does not exist." Is there a way to either create a custom page with an error message of my own, or a redirect to the gallery index when this happens, rather than the user getting this message?

Yeah, I can put that on the list. Which would you rather have? A good error page, or redirect to the index?

I'd rather see a good error page.

How about the option to pick either good error page or redirect to gallery???????

Cool.. I'd love the choice, but if I had to pick one I'd say redirect to index.

Error page with 5 second delayed redirect?

For usability issues, I think we should definetely have an error page. A redirect will just confuse people, and will never let anyone know what went wrong.

A good error page would say what went wrong, and give links to email admin, and to index page.

I concur with Skwid.
