Put your name or your logo on a picture before it goes anywhere. Do a whole batch at once.
Drop in as many as you like. They all get the same mark.
Type some text or load a logo, then choose where it sits, how big it is and how faint.
Each marked picture is listed separately. Your originals are untouched.
A mark tucked into a corner at ten per cent opacity is polite and useless — it crops off in seconds. If the point is to stop the picture being used without you, repeat it across the middle where removing it means damaging the image.
If the point is just credit on something you are happy to share, the opposite is true: small, in a corner, faint enough to ignore.
A logo with a see-through background sits on a photo far better than one on a white block. Save it as a PNG before you bring it here.
