Hey, I had this scrip from sometime now in the first skin, but it didn't work on the second so i had to get another, but This one is killing my site! When I add a JPG image it resizes it and convert it to .PNG which is much larger and heavier, could somebody please make it keep the images as they are? jpg to jpg, png to png...etc? Or get me another version of it that works with external images and keeps the extension as it is? Thanks a lot! <?php /* TimThumb script created by Tim McDaniels and Darren Hoyt with tweaks by Ben Gillbanks http://code.google.com/p/timthumb/ MIT License: http://www.opensource.org/licenses/mit-license.php Paramters --------- w: width h: height zc: zoom crop (0 or 1) q: quality (default is 75 and max is 100) HTML example: <img src="/scripts/timthumb.php?src=/images/whatever.jpg&w=150&h=200&zc=1" alt="" /> */ /* $sizeLimits = array( "100x100", "150x150", );
