Hi ! 
I remember when i was working on users' infos i was searching how to
retrieve contact pictures.
And while dumping packets sent by ICQ ... 2002 (or maybe 2003) i noticed
one was containing the picture. (i can't tell wich one ... I've got a
bad memory :op )
One client sent a jpeg picture to another... Maybe other files could
also be transfered this way ...
But .. I'm not sure ...

As my client is a web based one i finally used the www.icq.com/......
Url to retrieve pictures and haven't worked more on this point but ...
You should try it

Good luck

Howdy programmers,

I've been giving some small time to ICQ lite. As most of you probably
know its the new v9 client from mirabilis, and lacks of a huge amount of
features you can find in ICQ pro 2003A (also 
downloadable from mirabilis).

ICQ Lite doesn't publish any DC information in their status change,
their IP address as well as the DC port are zeroed.

When doing a file transfer over ICQ lite, the client will send a Type2
message with a MSG_GREET in it. The type2 message as its already
described by the database, has 3 extra TLV's.

TLV(3) with the file DC port.
TLV(5) with the ip address.
TLV(4) with something else.

- the COMMAND in a PEER_MSG (0x07d0,0x07da,0x07ee) equals the ACKTYPE in
a Type2 (0x0000,0x0001,0x0002).

Has anyone done any further tests? Is a NEGOTIATION possible with a v9
client? Im really tired and I have to get back to bed right now 

I remember reading about server-based file transfer packets a long ago
in this list, and I remember sniffing sometime a client sending
serverside file transfer requests (maybe when a proxy was

bah ill let you know if i find out something more interesting. rad2k
