Displaying blank pages for cbz containing folder

[savvasdalkitsis]

If the structure of a cbz file is like so:

 comic.cbz
    - comic/
            - page1.jpg
            - page2.jpg
            ...etc

The channel will display the comic, display all its pages but there will be no thumbnails and when opening the pages, nothing will be shown

If instead the cbz structure is like so:

comic.cbz
        - page1.jpg
        - page2.jpg
        ...etc

Everything works as expected.
