How do you do that to an image?

>>949947678
Not OP but its based on how the image is downscaled, when an image is resized, unless there is some sort of special resampling applied by the website it is shown on, its done by removing a grid of pixels.
That grid of pixels contains the other image.
There are online tools to do it easily and you can do it manually by calculation in an image editor.
What needs to be known is the size the image will be downsized to in order to figure out exactly where to hide the grid/other image.
