Put a picture in bottom right, fading with text if there is any

Question

• In a document, I'd like to have, on certain pages, a picture in the bottom right corner.
• I'd like the picture to not interfere with text (it can be displayed behind the text if there is text in the way).
• I tried this, but every time, I see only a part of the picture.
• Can you help me out so that the bottom-right corner of the picture coincides with the bottom right corner of the page?
