I applied SUPEE-10266 patch earlier but now I found changes in Mage_Core_Model_File_Validator_Image
file, Due to these changes Image size is getting bigger than actual size after upload. Can anyone please suggest the solution?
Thanks
Found a solution, In app\code\core\Mage\Core\Model\File\Validator\Image.php
imagecreatetruecolor function was creating a true color image.
