Exhibit plugin or other image plugin

I tried visiting http://www.redalt.com/downloads/ to download the Exhibit plugin, but I can not find a link to download the latest version. Is this plugin no longer being supported?

Do you have any recommendations for a image plugin that works with WP2?

I need to have the ability to place the image anywhere in the blog, automatically create a thumbnail, give the choice to align the image left or right, allow for CSS styling of the image and it would be cool if the image popped into a new window when clicked.

Thanks,
Shane
