Reply To: Cannot get Watermark working

Did you refresh page with your images after watermarking? Sometimes WP shows old (cached) images. Try to force-refresh (CTRL+F5) site or download images (sizes selected in settings) and check them for your own.

Please tell us which image sizes you selected?
Is it ‘specific custom post’ type or ‘all’ images?
Can you provide link to watermark and image?
