If you want to modify the code handling the processing of the watermark for the images, you want to edit the file administrator/components/com_hikashop/helpers/image.php and look at the _resizeImage and more specifically that code: Code: if(!empty($watermark_path)){ list($wm_width,$wm_height) = getimagesize($watermark_path); $padding = 3; $dest_x = $newWidth - $wm_width - $padding; if($dest_x < 0) $dest_x = 0; $dest_y = $newHeight - $wm_height - $padding; if($dest_y < 0) $dest_y = 0; $trnprt_color=null; if(in_array($extension,array('gif','png'))){ $trnprt_indx = imagecolortransparent($img); if ($trnprt_indx >= 0) { $trnprt_color = imagecolorsforindex($img, $trnprt_indx); } } imagealphablending($thumb, false); imagealphablending($watermark, false); $this->imagecopymerge_alpha($thumb, $watermark, $dest_x, $dest_y, 0, 0, $wm_width, $wm_height, (int)$config->get('opacity',0),$trnprt_color); imagedestroy($watermark); } The following user(s) said Thank You: [sr9yar](/forum/user/31971-sr9yar "View sr9yar's Profile") Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzMyLWNvbnRlbnQtY3JlYXRpb24vODc4OTU0LXdhdGVybWFyay1hZnRlci1pbWFnZS1yZXNpemU/dG1wbD1tYXJrZG93bg==) or [Create an account](/component/users/registration?Itemid=101) to join the conversation.
