I want to use the Watermark function on a new website but mot of the images are already watermarked because imported from a previous site. If I don't regenerate thumbnails, would I be sure that only the new uploaded images will be watermarked by the plugin?
What is the exact use of the Exclude folders options? For the uploaded images or/and for the thumbnails regeneration? Maybe it should more explicit. Or maybe this should be two separate and complementary settings.
More, I think it could be very useful to add a button to apply watermark in the edit screen of an image. It would allows to easily add a watermark to an already uploaded image.
