Hi SandMan,
I'm not sure what you mean by "relative" position. Relative to what? To you want it to move as the user scrolls so that it always stays in the current window? Or perhaps stay positioned relative to a particular cell.
Whatever the answer, it can be done. However, one problem with pictures that "float" over spreadsheets is that you cannot easily get to the cells underneath the picture manually without moving it first.
