Features / Usability

thanks, i need this to know the max widh of images i wan't to display in my left/right bar.
another thing, my page isn't alligning in the center of the screen.
with a 800x600 resolution its normal, but if i star to expand the window the page borders expand at the same rate and then one side starts expanding more than the other. i am using planetfall. you know where i can edit this?
thanks
