I'm a web developer on a Mac OS X (Mountain Lion) and was wondering if there is a (free) alternative to Overlay2 - basically it's an app that lets you create a floating window with a semi-transparent image on it that you can use for direct reference - I plan on using it to match my output code to what the designer had in mind, pixel by pixel. I often just move between tabs real fast but the position isn't the same and my eyes can only be that precise.

I just don't want to have to pay $25 for such a simple functionality.

Amazing how many people want to get paid by their clients but the software developers who write the tools to get the job done don't. Consider how much easier your job is with Overlay, how much time it saves, and then question how $25 compares. – samh yesterday
