Hi, i think the problem is coming from the imagepng function. Try check this http://www.electrictoolbox.com/php-fatal-libpng-error-zlib-error/
So you might try to set $generatedQuality variable after instantiating the helper to 9 or lower instead of 100 for png file, eventhough this is bad practice as no setter function for $generatedQuality in the class.

You may consider dividing $generatedQuality of 'png' by 10 as long as it can make < 10, in the line 145.

Code: Select all

case 'png':
                return imagepng($img, $file, ($this->generatedQuality / 10)-1);
                break;
