Roboreader is a fast and free advanced sequential image viewer. It is designed to replace the default windows image viewer while offering many new features and at the same time running faster. Roboreader supports animated GIFs in addition to standard JPG/JPEG/JPE/JFIF/BMP/PNG/TIFF/TIF/ICO files. Additionally, Roboreader can view all supported image files directly out of 7z/ZIP/RAR/CBR/CBZ archive files. Being a sequential image viewer, Roboreader will automatically continue to the next archive in the directory after viewing all images within an archive.
