I wrote a small function like the following to create my won thumbnails. function make_tumb_nail($url){ $size=GetImageSize("image/$url"); $ht=$size[1]; $wd=$size[0]; if($ht>$wd){ $h=$ht; for($i=1.01;;){ if($h<121){ break; } $h=$ht/$i; $w=$wd/$i; $i=$i+0.01; } } else { $w=$wd; for($i=1.01;;){ if($w<91){ break; } $h=$ht/$i; $w=$wd/$i; $i=$i+0.01; } } $wd=floor(round($w)); $ht=floor(round($h)); $returnstring="width=$wd height=$ht border=0"; return $returnstring; } This function returns the thumbnail width and height as string and use it along with the original string. <img src="image/<?php $url ?>" <? php make_thumb_nail($url) ?>> Hope this helps.

Greetings.
    Is there any quick way to generate thumbnails of existing pictures in a
directory? It would seem quite worthless to create 120x120 images of ones that already exist, and upload duplicates.. Therefore, dynamic thumbnails would be perfect. Any solutions?
    PHP 4.0+ thanks.
