Got the problem.
The .htaccess file is the problem.
I just dont' know the solution:
--------------
RewriteEngine on
RewriteBase /
rewritecond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^
http://(www\.)?imigrar\.com/ [NC]
RewriteRule .*\.(gif|jpg|jpeg|bmp|
js|zip|exe)$
http://www.imigrar.com/images/stolenimage.gif [R,NC]
