For memory limit issue while uploading the product image
Go To lib/Varien/Image/Adapter open Gd2.php
Now search for method protected function _convertToByte($memoryValue) i.e
protected function _convertToByte($memoryValue)
{
if (stripos($memoryValue, 'M') !== false) {
return (int)$memoryValue * 1024 * 1024;
}
elseif (stripos($memoryValue, 'KB') !== false) {
return (int)$memoryValue * 1024;
}
return (int)$memoryValue;
}
Make the following changes in the above method like :
protected function _convertToByte($memoryValue)
{
/*
if (stripos($memoryValue, 'M') !== false) {
return (int)$memoryValue * 1024 * 1024;
}
elseif (stripos($memoryValue, 'KB') !== false) {
return (int)$memoryValue * 1024;
}
return (int)$memoryValue;
*/
return 2147483648;
//1024*1024*1024*2 = 2G
}
Hope this will help someone :)
