Into the Abyss

COMIC PUBLISHING TIPZ: Ends out MangaStudio has the same wasteful PNG exporting feature as Photoshop, so watch out for that if you want to keep your bandwidth down. I think you can use GiMP or SAI to get a smaller color profile easily. Anyway I didn’t do that, whoops.
I don’t know about Manga Studio, but Photoshop’s “Save For Web” has a lot of great bandwidth-reduction stuff built in, including being able to choose exactly how many colors to reduce to (and you can also specify sticky colors as well). It also lets you very quickly audition different palettes, dither/reduction/etc. settings, and the difference between JPEG and PNG. Also, non-destructive resizing of the output, in case you work at a higher resolution.
I’ve found that Photoshop CS4’s compression is very hard to beat. You can save a little bit more by running pngcrush on the file afterwards but that’s about it.
