RE: [PHP] image code

I wrote thumbnailing script that did exactly what you said below, but to eliminate the needless regeneration of existing thumbnails I just did a check to see if the thumbnail already exists: if(!file_exists("/path/to/thumbnail.jpg")){ //Create the thumbnail here } If the thumbnail already exists, the script skips over it, but if it doesn't it creates it as needed. -Andy > -----Original Message----- > From: Hugh Bothwell [mailto:hugh_bothwell@hotmail.com] > Sent: Tuesday, June 19, 2001 1:02 PM > To: php-general@lists.php.net > Subject: Re: [PHP] image code > > > Seems pretty straightforward, actually; I would write a script > that takes as > parameters the name and desired size of a graphic, resizes it, and returns > the thumbnail ( look at ImageJPEG() ).
