What is the reference-image?

Zachary Wolf	Very useful. [Version 1.4]
	I've had this for a while now and I use it every day that I do layouts. My only complaint is that the bottom marker has a fuzzy edge, making it hard to tell which pixel it is on sometimes. Overall, very useful.

Simon Abramson	Cheap, simple, reliable [Version 1.4]
	I've enjoyed this tool -- it's cheap and simple. Sure there's some functionality I'd like to see added, but for the price this is a great tool.

Michaux Kelley	A good, inexpensive screen ruler. [Version 1.2]
	My only quibble, and not enough to drop it to 4 stars is: the edges of the tool are sometimes lacking in contrast. An excellent, and much appreciated update, would be to add some setting or preference for adjusting the color of the tool's edge (and possible some zoom functionality).

	Works perfect just what I have been looking for. As a web developer I always need to know how many pixels something is and this is perfect for it.

BloodyMike	Good tool [Version 1.0]
	A good tool to measure graphic on screen when developing or creating graphic. I would give it five stars if I could move the measuring tool with the cursor keys.
