Displaying a photo for an Application endpoint

Hi everyone,

Here is my problem :
I work on a big UCMA project since 3 month and now I would like to add a little feature.

I have a lot of ApplicationEndpoints which can be added, modified or deleted dynamically and I would like, each time that I create an ApplicationEndpoint, to specify a picture which will be displayed on Microsoft Lync.

I already have a lot of other functionnalities but I'd really like to have this one.

I searched for days but I didn't find anything so before telling myself that it can't be done, I wanted to ask !

Does anyone know if that is possible ? In that case, could you show me the way to do it?

Thank you
