Hi. Thanks for the request. Image watermarking is not currently a feature of Files app, but definitely something I might consider. May I ask, are you looking to add watermarks to all images, both the originals (visible on zoom) as well as the resized images? Logically that means that Files app would have to re-process all your original image files, adding watermarks, re-compressing JPG and re-saving, overwriting the originals. As of now, Files app is "passive" and doesn't modify the folders (or any files within), but watermarking would require modifying all uploaded images. Thoughts?
