Correct reader for epubs and manga on C67ML Carta 2?

Hi guys.

I just got a C67ML Carta 2 and am really enjoying it. However, I am noticing that Oreader and Neo Reader (the only 2 pre-installed readers) both seem to lack any settings or configurations related to images. This is a problem for me as I prefer my images to fit to width when I am reading epubs.

Are there some settings that I am not aware of to fix this issue? Or are there other readers you can suggest that I install that have better support such features and options?

Additionally, I am looking for a good comics reader. Most of my comics are in RAR or ZIP files. Back on my T68, I remember using Perfect Reader, but it did have some issues. Can anyone suggest a better reader?
