It doesn't quite work like that.
We do not do your work for you.
If you want someone to write your code, you have to pay - I suggest you go to Freelancer.com and ask there.

But be aware: you get what you pay for. Pay peanuts, get monkeys.

The idea of "development" is as the word suggests: "The systematic use of scientific and technical knowledge to meet specific objectives or requirements." BusinessDictionary.com[^]
That's not the same thing as "have a quick google and give up if I can't find exactly the right code".
So either pay someone to do it, or learn how to write it yourself. We aren't here to do it for you.

A (hopefully) intuitive (but also very naive) description how one can do this.
a.) Let us assume you have a picture where every pixel is defined by RGB R=8Bit/G=8Bit/B=8Bit.
b.) Let us also assume your picture is enough big compared to the watermark you like to embed in it.

Now let us "steal" the LSB (least significant bit)of each pixel's RGB Value and use it to store the watermark in it. Manipulating the LSB will usually not bee visually recognized. See this on wiki, how a picture of a cat is embeded in a picture of a tree: Steganography - Wikipedia[^]

That describes only the idea behind watermark. In praxis it becomes a little bit more complex. This e.g. how to protect the watermark not to be detroyed by e.g. image resizing.
