One more version of setMemoryForImage (see below)
<?php
function setMemoryForImage($filename)
{
$imageInfo = getimagesize($filename);
$memoryNeeded = round(($imageInfo[0] * $imageInfo[1] * $imageInfo['bits'] * $imageInfo['channels'] / 8 + Pow(2, 16)) * 1.65);
$memoryLimit = (int) ini_get('memory_limit')*1048576;
if ((memory_get_usage() + $memoryNeeded) > $memoryLimit)
{
ini_set('memory_limit', ceil((memory_get_usage() + $memoryNeeded + $memoryLimit)/1048576).'M');
return (true);
}
else return(false);
}
?>
//work's it. no problem!
