I'm trying to fix a Canon 17-40mm with loose screws under the zoom ring.

I saw that there is a simple way to replace the screws on the zoom ring of the 17-40mm Canon zoom lens. I slipped off the cover and have one of the loose screws. The other is still in the lens.

Does anyone have images of where they go and how to achieve this?

Yes, there is a nice visual guide here explaining how to disassemble the lens. Follow it to fix yours back into shape.
