Using the FileBrowserTV app you can view any CBR, CBZ or images stored in a zip or rar file as a comic. Let me show you how.
Connect to your computer using FileBrowserTV
You can download a free trial of FileBrowserTV here
If you double tap the image you can preview the pages for the entire cbz or cbr file. Select any image in the index to go straight to that page. And that's it.
