Attachment Fu lets you store uploaded files in your database and easily access through as a Rails model. If your files are pictures, you can easily resize and/or convert them using Attachment Fu.
You can find out more information at chapter 3 of our book, Practical rails Plugins, or at a popular Attachment Fu Tutorial, http://clarkware.com/cgi/blosxom/2007/02/24#FileUploadFu.
