Sequential is an image viewer for Mac OS X. It was originally designed for opening a folder of images and displaying them in order. It works well for viewing comics and manga.

Sequential can display folders and archives (ZIP, RAR, CBZ and CBR) of images (including JPEG, PNG, and GIF) and PDF files. It is able to load images on the Internet from a page or image URL.
