Thanks. The only way to resolve was to do a Bulk Action “Reset” for each gallery which removed the original watermark and then do a Bulk Acion “Set Watermark”
That’s the odd thing…. watermarks only appear when you click on any thumbnails to open the gallery, then open one of the thumbnails in the gallery. Then when the Lightroom browser opens some of them have a watermark and when they do it appears in 2 different locations ( centre and bottom center)
Is it possible to display the gallery of thumbnails, as is on my website, but when a user clicks a thumbnail it opens the image browser for that album?
