This plugin allows to add a watermark on all your images, even the ones already uploaded.
YES, you can ! The watermark is applied in a way that doesn't modify your original picture. By deactivating the plugin, the watermark will be removed everywhere.
It's due to cache. Your browser keeps in cache your images. You should empty your browser cache and try again to check, it should solve the issue.
Once the plugin is activated, the watermark will be applied in all your pictures following the settings you chose previously.
