Free app to view .cbr files on iPod Touch

Hi all

I'm looking for the best free app to view .cbr files on the iPod Touch.

I've tried extracting the .jpegs from the .cbr file, but then when I put them on the iPod, the quality of the files is really terrible and practically unreadable.

So any apps or other solutions?

Is there than perhaps any way to make the quality of the .jpegs on the iPod better?
