There are some admin styles issues that are being worked on and issues with the "Locally" option of the gallery that relate to Wordpress 2.5. I hope to have these adjustments very soon.
PhotoXhibit, formally Benjamin Sterling Galleries, was born out of the fires of so many not-so-great gallery/image manager plugins for WordPress.
This plugin uses photos from your Flickr, Picasa, and/or SmugMug accounts as well as allows you to upload and build Albums to help you build inviting Photo Galleries on and through out your site.
Full support will be handled at the PhotoXhibit website
