xfce4 file associations

[Blue Raccoon]

Hi,

Newbie question:

Does xfce4 maintain file-type associations?

For instance, in Sylpheed, when I click a link in the about box or choose 'open' for an attached jpg nothing happens. Apparently url's and jpg's are not associated with any program. But I wonder if xfce4 bothers with that. 'Lite' comes at a price, perhaps. I have not been able to dig up any relevant info on the net.

thanks,
