Images in themes are not rendered correctly

[JW]

In some installations of Chameleon, images in the theme are not loaded correctly when loaded using the URL http://example.com/blog/images/image.png.

This bug is not always reproducable, and various things can happen instead of the expected action:
- The image may not be rendered at all, and sometimes can cause the server to crash (this happened to me using Rails 1.2 and Mongrel).
- The image can be rendered as gibberish (the image is interpreted as plain text instead of as an image).

This bug happens because Chameleon and Rails don't always send the correct MIME type in the HTTP header Content-Type. Either Rails or the webserver add a Content-Type themselves, which often is text/html.

This bug is fixed in Chameleon 0.6.2 (currently, the fix is not in the trunk yet, but still in the rails-1-2 branch).
Instead of the render() function we used previously, we now use send_file(), which is designed to send binary files to the browser, of any type.

Fixed in trunk.
