Using --disable-web-security switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using --allow-file-access-from-files switch?

On Windows:

chrome.exe --allow-file-access-from-files

On Mac:

open /Applications/Google\ Chrome.app/ --args --allow-file-access-from-files

startup chrome with --disable-web-security

On Windows:

chrome.exe --disable-web-security

On Mac:

open /Applications/Google\ Chrome.app/ --args --disable-web-security

This will allow for cross-domain requests.
I'm not aware of if this also works for local files, but let us know !

And mention, this does exactly what you expect, it disables the web security, so be careful with it.
