Thus, we have problems like this one: https://stackoverflow.com/questions/20614686/gd-warning-product-of-memory-allocation-multiplication-would-exceed-int-max I would propose going in and updating the integer definitions to accommodate 64-bit processors and its larger memory space, but GD isn't my forte so I'm not sure if I would break all of the things if I went in and patched it. Test script: --------------- echo PHP_INT_MAX . '<br/>'; echo 174400 * 249600 . '<br/>'; $img = imagecreatetruecolor(174400, 249600); Expected result: ---------------- 9223372036854775807 43530240000 Warning: imagecreatetruecolor(): gd warning: product of memory allocation multiplication would exceed INT_MAX, failing operation gracefully in /home/bartek/Documents/WWW/WOF/application/controllers/EditorController.php on line 5 Actual result: -------------- <b>Parse error</b>: imagecreatetruecolor(): product of memory allocation multiplication would exceed INT_MAX, failing operation gracefully ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66488&edit=1
