Interestingly, this was part of the original design spec for the Directory view but the picture thumbnail was dropped to keep the page lighter. It been a while and connectivity has improved for most users. I think it's time for us to review the decision and bring the image to show up alongside the person in the directory listing. Thanks for bringing this back to our attention, we will take this up.
Request you to pls. upload the Employee picture as well, when an Employee tries to find some other member through 'Employee Directory'. This will be helpful for members who immediately get deployed at client site post their joining.
