This article will go over how to add watermarks to your images. Please note that you can add watermarks to future images, but not images that already exist in the media folder.
Click Settings.
Click Configurations.
Click the Website tab.
You can see the watermark manager at the bottom. You can enable the function as well as upload the watermark.
Since the px size of an image would affect how the watermark looks you can adjust your watermark to look better based on the px size of the original image.
5. Once you have enabled the status for watermark as well as added your watermark images, you MUST add the image to the proper place.
Click Catalog.
Click Products.
Select a product.
Click the Files tab.
Upload product images.
If the image already exists in the media folder it will not apply the watermark. The reason is the watermark has to be applied at the time of the upload, so images cannot be retroactively fitted with the watermark.
Even after you have enabled watermarking, if you upload through the Media Folder and then attach it to the product, it will bypass the watermarking.
