Google (XML) Sitemaps Generator
This plugin will generate a special XML sitemap which will help search engines like Google, Bing, Yahoo and Ask.com to better index your blog. With such a sitemap, it’s much easier for the crawlers to see the complete structure of your site and retrieve it more efficiently. The plugin supports all kinds of WordPress generated pages as well as custom URLs. Additionally it notifies all major search engines every time you create a post about the new content. Learn more
Discontinued: A9 SiteInfo Generator
This plugin was building a A9 SiteInfo menu for your WordPress blog. A9 removed the SiteInfo functionality from their toolbar and no browser implemented it since then, therefore this plugin is also not relevant anymore.
Discontinued: ImageShack Uploader
This plugin supported uploading images to ImageShack directly from the WordPress writing screen. Since ImageShack is dead, this plugin is not supported anymore.
