The HTML Import 2 plugin can take a directory of static html pages and import them into WordPress as posts or pages. I did some experimentation with the plugin and found that it did the job as advertised.
I was able to import the static pages as posts and assign them all a tag. The plugin also supports assigning the posts a category. Images were also placed in the media library. See below for a screen capture of the content settings I used for my experiment. This might come in handy for importing photo bucket albums into WordPress.
