How does OS X apply this warning and what's the best way to disable it?

I'm a Web Developer and more than understand the risks of teh interwebs.

FYI, anyone can embed images. Just use the HTML: <img src="" /> – Nathan Greenstein Feb 26 '11 at 15:50
@nathan-g Thanks, but I think I need just a little more rep before that restriction is removed :) – PhilSwn Feb 26 '11 at 16:31
@nathan-g Ah, nm, I leveled up! – PhilSwn Feb 26 '11 at 16:59

Use the Terminal and this command:

defaults write LSQuarantine -bool NO

That will disable warnings completely after you restart the system. To reverse it, run it again with "YES" instead of "NO".

Or you can create a custom listing of safe files with the method described here:

Custom assessment file for downloaded files

How does OS X decide to apply the Quarantine? – PhilSwn Feb 25 '11 at 21:00
-1 for admonishing the OP. It's not safe to assume they didn't check Google first because the same could be said of every question on the SE sites. – Philip Regan Feb 25 '11 at 21:57
