FeaturedImage is the finder that extract featured image from a web page. FeaturedImage::Finder accesses and analyses a web page using Mechanize, download images which are referenced by IMG tag in HTML, and specify a featured image based on size of image using RMagick. Furthermore, FeaturedImage contains pretty good thumbnail generating function too. FeaturedImage::Converter crops centered area of image, resizes, and convert to arbitrary format automatically.
