Getting a User's Buddy Icon

Step #1 - Finding the icon for a user

First the client will need to discover what the Buddy icon BART ID is for the user. Depending on display, the client will want to look inside the USERINFO for either the ICBM__CHANNEL_MSG_TOCLIENT SNAC or BUDDY__ARRIVED SNAC. The USERINFO will contain an array of BART IDs and the client should select the one with the BART__ID_TYPES Class for which it is looking.

Step #2 - Connecting to BART

If the client is not already connected to the BART server it will need to do so.

1. Send a OSERVICE__SERVICE_REQUEST to BOSS with the foodgroup of BART.
2. Wait for a OSERVICE__SERVICE_RESPONSE from BOSS.
3. Using the RECONNECT_HERE tag, connect to the BART server.
4. Using the LOGIN_COOKIE tag send a FLAP SIGNON packet, just like connecting to BOSS.
5. Send a OSERVICE__CLIENT_ONLINE SNAC to the BART server.

Step #3 - Downloading from BART

Once connected to BART, use the BART__DOWNLOAD2_QUERY SNAC to download as many assets as required.

Step #4 - Display Icon

Display the image.

From Aleksandr Shutko: Upload/download server-stored buddy icons (SSBI) sequences

OSCAR sequences

Upload/download server-stored buddy icons (SSBI) sequences        SSBI service allows clients to store and retrieve little buddy icons called ICQ avatars. Icon size is limited by size of flap packet (~8kb). Every icon has unique combination of id (word), flags (byte) and md5 hash. AOL BOS server doesn't support SSBI service so you should request it and setup as described here.      To upload own icon to server you should calculate icon md5 hash and store it as ssi type=0x14 item. Then you'll get SNAC(01,21) with icon flags bit8=1 - this is a command for you to start icon upload. Here is the sequence description (example dump):  Upload own icon to server   >>   SNAC(13,08)   [BOS] User add icon id/flags/md5 hash to server (ssi type=14)   <<   SNAC(13,0E)   [BOS] Server reply command ok (errcode=0x00)   <<   SNAC(01,21)   [BOS] Server command to upload icon (icon flags bit8=1)   Client check/prepare SSBI connection   >>   SNAC(10,02)   [SSBI] Client sends icon to server   <<   SNAC(10,03)   [SSBI] Server reply with icon id/flags/md5 hash or with error   All your buddies will receive SNAC(03,0B) with TLV(0x1D) here   <<   SNAC(01,21)   [BOS] Server ext status notification (icon flags bit8=0)     To download icon from server you should know user uin/screenname, icon id, icon flags and its md5 hash. You can get all needed information from SNAC(03,0B) containing TLV(0x1D). Official ICQ clients also use SNAC(10,06) to get client own icon after receiving SNAC(01,21). Here is the sequence (example dump):  Downloading buddy/own icon from server   >>   SNAC(03,0B)   [BOS] User status notification from server (with TLV(0x1D))   Client check/prepare SSBI connection   >>   SNAC(10,06)   [SSBI] Client sends icon request to server   >>   SNAC(10,07)   [SSBI] Server reply with requested icon
