Okay.
FF:
Firefox cant find the server at img.desmotivaciones.es.
Check the address for typing errors such as ww.example.com instead of www.example.com
If you are unable to load any pages, check your computers network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Chrome:

Oops, copy/paste didn’t work right, the Chrome message is the same as it has been: site can’t be reached etc.
