The firefox image-loading thing is something I've noticed at one point (it's since gone away). Images load just fine on chrome, opera, or (dare I say it) IE... but at one point on firefox, even when the image was LOADED, it didn't fully RENDER until you scrolled down and gave it a second or two.
I thought it was just a firefox-nightly issue, but if you're having it as well I don't know what to think. I'd be hesitant to put the blame on Batoto though.
Lastly, please refrain from hijacking a support thread. If you are having an issue unrelated to the original post (page freezes in chrome) please make a new thread. Thanks
