No, there is no such thing.
A photo either has the watermark, or it doesn't, it can't change itself when someone downloads it.
For that you need to make sure that the same image not getting downloaded.
Like you can show images with watermark however the download link that you are providing to a customer that should be different.
Thank you. So you are saying that there is no way for me to hide the watermark when I personally upload it to my website. Not only does it either have one or not, but it is either always visible or not. Clearly I am a novice and I need expert help.
I don't want every photo I upload to the gallery of my website (which is not a photography site but a general one), to a have a watermark. That is distracting ans seem s like overkill. But I also don't want the public to be able to download/copy my photos and use them as their own. Is there any way to deal with this?
One thing you can do is NOT upload the full size image. If you upload a scaled down version of the image, say 1200 images on the long side, this limits people from printing the photo at a large size ...
once the photos is on the internet, there is no way to stop people from making a screen capture of your scaled down version of the image and using that for whatever they want.
So, you have to choose between not putting your photos on the internet, or putting them on the internet which possibly allows the scaled down images to be used.
