[SOLVED] how to access $config['base_url'] in my controller?

[eluser]ppeemm[/eluser]
just a quick one: I need to store the URL of a picture in my database and I am wondering if I can access this config variable here ($config['base_url']) which contains the begining of the URL?

if so, can can I do that from my controller?

cheers
