Roboreader

oboreader is a pretty simple image viewer that supports any of the following formats without any trouble at all: CBZ, CBR, RAR, ZIP, 7z, GIF (animated images), JPG, JPEG, JPE, JFIF, BMP, PNG, TIFF, TIF, and ICO. You can select the application as the default image viewer, or drag the pictures to Roboreader's icon to open them. You can also open compressed files, and preview the images inside as slides, without having to unzip them. Roboreader is a great application. It's light, discreet, fast, and compatible with almost any image format you can think of. It's an excellent alternative to the default image viewer in Windows.
