Okay, winrar is a compression program, a zip file is a compressed archive, a jpg file is (generally speaking) a compressed image, and when you stash a bunch of compressed images into an archive using a fairly loose compression method your total file size will not decrease or may even increase a little. That is as clear as I can make it.

I suggest you run "comic2lrf" (just that, no parameters) on a commandline and note the many options it had - as far as I know most if not all of these options can be set somewhere within calibre too. I will grant you that not every option seems to be in the same place in the GUI.

I have an 8 Gb memory stick, I couldn't care less about a few MB more or less, and you might want to experiment with the various options of comic2lrf. It took me several experiments to find a setting I like, and sometimes the settings which are fine for one comic need to be tweaked a little for the other.
