The watermark is added to the photos during their upload them to the gallery.
You can change the watermark and adjust its opacity in an existing gallery.
To do this, click My Account (in the upper right corner), then "Settings", and select "Watermark" (https://app.mafelo.com/settings/watermark).
Change the design and opacity of the watermark in Mafelo settings; you can check the result of selected settings in the preview window.
Click “Save”
Go to the "Photos" tab in the gallery in which you want to update the watermark and add photos of your choice again.
IMPORTANT! Check the "Replace previous photos with the same names” box, otherwise the files and watermark will not change.
The watermark in the client's gallery will be updated.
IMPORTANT! On the preview of photos in the gallery, you may see a different watermark than the one you have set. To see the actual watermark, click on the thumbnail to enlarge the photo.
