I have a PSD which I've opened up in Gimp (because I currently don't have Photoshop) and I am having difficulty with locating any functionality on the Gimp UI that would help determine the positioning and dimensions of a given element in any layer. Is there anything that could provide me with a way of finding the position and dimensions of the individual elements?

Any advice that would help assist would be greatly appreciated... I am not graphic-design orientated, but have some understanding of Gimp...
