Trying to add a picture without a background but keeps turning black.

I'm trying to add a picture on my drawing that I want to use as a watermark. I have already changed it so its transparent and it has no background. When I add it in, it just turns into a black rectangle with a faint outline of the text in the picture. Basically just need to know how to add a picture into my drawing without it changing. I might need to change the file or something?
