Great extension, specially for archiving galleries for offline use in dynamically generated pages. I don't give it five starts only because of two thing: 1.- it defaults to create a folder with the name of the target domain, and 2.- it forces the generated files to have default names ended with ".zip" (having to rewrite them by hand in case one wants to save with other extensions like cbz or xpi). If somehow these behaviors could be disabled, it would be the perfect extension for this task.
