I am using phpThumb class to generate thumb image and watermark image/text; I am getting thumbnail image successfully but not able to write any watermark text or image.
<img src="phpThumb.php?src=<?php echo $row['user_profileid']; ?>/<?php echo $profile['photo_name']; ?>&w=144&h=173&fltr[]=wmi|watermark.png|BL" alt="" class="profile-pic">
I have to change in config file to show watermark ??
