Window/Page/Browser/Screen width

Hi, I've seen similar questions in archives so sorry if I'm asking the same thing again! Is it possible, using php, to get the screen, page, or window width? My aim would be to have a set of picture thumbnails, and give the html the best number of columns depending on the size of the display. I'd rather not use java, because many people have it turned off (even though I wouldn't be exploiting it!) Cheers, --Rick __________________________________________________ Do You Yahoo!?
