re: memory exhaust error when using imagecreatefrompng

hi all i am just trying to run a simple script to resize a png file and am running into some errors i am using php 5.1.0 (also tried on php 5.1.0RC6) i posted this on bugs.php.net, but they said that it wasn't a bug http://bugs.php.net/bug.php?id=35348 just wanted to know if anyone else had this kind of problem the memory limit in php.ini is 8MB i bumped it up to 128M, and I still get the same error could it be an issue with my setup somehow? as i said in my bug report, on windows using php-5.0.2, it works fine and imagecreatefromjpeg works fine on windows and linux, so i'm not sure what the issue is with imagecreatefrompng possibly something to do with how i installed gd/zlib? any advice thanks dave
