Huh, I have the same problem. Could it be related to using developer channel of Chrome? (I'm currently on version 13.0.782.10, still same problem.) Apparently the images making up the page get a CSS width and height of 1 pixel, for some strange reason. In some cases I've had it do that for half a chapter, but in most cases only on the first page.
I now usually work around the problem by opening up an incognito mode window to show just the first page (without any plugins loaded), then read the rest of the chapter (which, as I stated, usually works fine).
Okay, I found out that it is related to Adblock Plus. When disabling Adblock Plus it seems to work just fine! Adding mangastream.com and img.mangastream.com to the Adblock Plus whitelist doesn't seem to help either.

I guess maybe I'll switch it out with other adblockers and see if any of those works better...
