It's possible for an admin to upload the picture on behalf of the guest users. However this should be self service (or some kind of consent to fetch from the original Azure AD instance).
I would suggest that Microsoft implements a way for guest users to self-service add a profile image using either a sharepoint site/portal or the teams client.
This feature request is now in the planning stage. As more details become available, I will post them here.
We know you are patiently waiting for this feature. This feature is being implemented in stages. Fast tenant switching is currently in testing both internally and with early customers. We expect to release to the public in the Fall. I’ll post an update once it’s rolling out.
Full multi-tenant, multi-user support will be added after fast tenant switching.
