Image resizing takes a lot of cycles. As opposed to generating a thumbnail every time a visitor comes to your site, cache it. /* PHP Psuedocode */ thumbnail_file = thumbnail-cache/product.png if(file_exists(thumbnail_file)) print <img src=thumbnail_file /> else generate_thumbnail(source, thumbnail_file); print <img src=thumbnail_file /> This way, the expensive GD hits only take place once, when the thumbnail is first created. Otherwise, you may get a visitor who constantly refreshes and drives up your load average -- and on shared hosting, this can be problematic. -- _ (_)___ Jed Smith, Code Ninja | / __| RFBs: [email for info] | \__ \ +1 (541) 606-4145 _/ |___/ jed@jed.bz (Signed mail preferred: PGP 0x703F9124) |__/ http://personal.jed.bz/keys/jedsmith.asc
