For a simple way to add attachments to your models I recommend that you use attachment_fu. In this tutorial I’m going to walk you through how to attach images to a User model, so a User can have a gallery of images. The attachment_fu plugin is by far the best I have seen for adding attachments such as PDF, DOC, ZIP files and more importantly images. attachment_fu supports mutliple storage types for your attachments (database, filesystem and amazon s3). It automatically creates thumbnails for your images using different processors (ImageScience, RMagick and MiniMagick). Supports vaildation, such as minimum size and the content type.
