If someone already asks this kind of question, please take my apology.
We have one png image file that we would like to use for our certificate
and all the signature, seal, and watermark are on it.
Is there any way that I can simply replace a Moodle certification image with the one that we have for a certificate customization? Do I have to crop the watermark, signature, and seal separately in Photoshop and upload to each folder???
Also, how can I save the image as png-8???
