I am trying to make a preview of a wall projection for the user.
The user uploads an image and it is then layered on top of a wall image, similar to what I have uploaded here. Only lighter areas are visible such as white writing and colours, black areas are completely transparent against the wall.
I cannot find any plugins that allow this but I’d be grateful if you know of one. I am guessing CSS is the best way but I am struggling to find a good tutorial.
Thanks In Advance!
