Usually the userphoto is could be stored insite jpegPhoto LDAP field, or you could use another repository like IBM Connections profile photo. To check and configure the server behavoir, we have to use the Sametime System Console and open the relative server configuration.
Sametime Meeting Server
Out of the box Sametime Meeting Server is set to use jpegPhoto field inside LDAP by the following 3 fields: userInfoImageAttr, userInfoRedirect, userInfoUrlTemplate
If we like to switch to IBM Connections Profile pic, we have to set true userInfoRedirect and set Connections URL inside userInfoUrlTemplate like this:
Sametime Proxy Server
Sametime Proxy use by default Sametime Business Card who is set inside Sametime Community server configuration where typically you have to use the jpefPhoto field
If we like to switch also here to IBM Connections Profile pic, we have to set the correct URL inside the Sametime Proxy configuration using Sametime System Console
You could retrieve the user's photo passing the correct attribute to photo.do , modifying the URL eg /photo.do?uid= or /photo.do?uid=
Sametime Connect - Sametime Embedded
IBM Sametime Connect client or Sametime Embedded Notes client are using the configuration of community server so they check the jpegPhoto field in LDAP directory..
If you don't like to insert (or you could not insert...) the photo inside LDAP , you have to install the Connections Plugin for Notes , or the plugin for Sametime Connect, and you could find this on Greenhouse catalog
The Notes plugin is still up to date with last supported software and installing that you could have also the IBM Connections Business cart (and the user photo) on your client.
The Connections plugin for Sametime Connect is not updated like the Notes Plugin but as you could see on the catalog is still working with Sametime Connect 9 and IBM Connections 4.5
