I like to read comics (or manga), especially japanese comics chinese translation, such as One Piece, Bleach, Naruto, Ah! My Goddess, and other else.
What software are you using to read those comics? I suggest this one: ComicsViewer. I think it is the best one to read comics. However, one might feel hard to control the program, like the first time I used the program.
To read turn the page from page, you can just use both “” keys. If you like, you can just customise the keys.
To scroll the page, you just use the arrow keys. However, the scroll speed may be slow. So, go to “Options>Page Show”, then you can change the scroll speed.
If the quality of the comic image files is not good, you can press “p” and adjust the image quality until you see it is fit.
It can view the image files in .zip and .rar directly.
