hello,

im new to php and im trying to make a photo gallery following a tutorial i found on a site i ccant remember address to. well hte code below is short. but i dont get the whole thing.
first of all i would like someone to explain me what is going on in the while loop in detail. also i dont get the poiint with the fp variable. doesnt look like its been used.

also how can i make the script find the image size and open the new window accordingly? and while we're at ti, i woul like to have a limiteation on the number of thumbs on one site, so that the script wil make display a link for the rest to show.

sounds like a lot, but would be greatful any help.

thanks a lot guys
kumar

while($entry=$dir->read()) {
if($entry == "." || $entry == "..") {
continue;
