Many web design types use a masked browser chrome to present their design work to clients - it helps provide a context for the visuals being presented.

I personally find it a tremendously useful technique to use from the very start of a design process - it keeps me aware of how the elements I'm producing will sit within the browser, and ultimately of how they'll appear to the end-user.

I've done several versions over the past half-decade or so, but finally got around to doing one with multiple chrome options, layer group masks, etc., which makes it all ludicrously easy to use. Even better, the chrome is nicely drop-shadowed and pretty much presentation-ready!

All you need to do is grab the .psd and use. Instructions are in the first group. If you find yourself making improvements (such as adding browser versions), do ping me!
