Spiderfish traverses websites and downloads all files it finds (e.g. gif, jpg, mp3, etc.). To search a particular webpage, put the webpage's URL into the Webpage textbox, set the Download Directory, and push the "Go" button. All files found by Spiderfish will be put into the download directory. Spiderfish v2.0 incorporates many features, including the ability to run SpiderFish in command-line mode, control over the size limits of downloads, etc. See the site for details!
