In my .htaccess file, I have placed the following : RewriteEngine On RewriteRule ^images/([0-9]+)$ image.php?id=$1 [L] RewriteRule ^images/(.*)$ image.php?filename=$1 [L] This allows either: http://localhost/images/5 or http://localhost/images/myimage.png to work. I prefer the filename as it looks cleaner and appears to be more standard. So, in a webpage, I can now add the following html code to show the image. <img src="http://localhost/images/myimage.png"; /> -- /*************************************** * Robby Russell | Owner.Developer.Geek * PLANET ARGON | www.planetargon.com * Portland, OR | [EMAIL PROTECTED] * 503.351.4730 | blog.planetargon.com * PHP/PostgreSQL Hosting & Development * --- Now supporting PHP5 --- ****************************************/
