No error returned when external url NOT in allowed list

[GoogleCodeExporter]

What steps will reproduce the problem?
Have an image src url that is hosted on a server NOT in the $ALLOWED_SITES array

What is the expected output? What do you see instead?

I would expect either it gives an error much like the image is not found or the 
default image is shown as if no image found in post

What version of the product are you using? On what operating system?
I am using script version 2.8 and wordpress 3.2.1

Please provide any additional information below.

If you right click the image and open in new tab you will see it shows you an 
error. I think this is a good enough error report for you to debug the problem.

Thanks. I would never have thought to view image to see the error message.

I do seem to have another issue. When I filled in the error image to use then I 
get this error instead:

It says "The image 
'http://www.dougberger.net/wp-content/themes/dougTooldv/scripts/timthumb.php?src
=http://punditkitchen.wordpress.com/files/2008/09/political-pictures-barack-obam
a-chill-out-got-this.jpg&w=100&h=100' cannot be displayed because it contains 
errors"

I have this set:
if(! defined('ERROR_IMAGE') ) define ('ERROR_IMAGE', 
'http://www.dougberger.net/wp-content/uploads/2011/08/dougsviews.jpg');

but it still gives me the error noted here.
