Import User Photo to Active Directory

If you want to have an image in Outlook, Skype for Business or SharePoint you can use the attribute thumbnailPhoto in Active Directory.

Doing it with Powershell:
Import-Module activedirectory
$UserPhoto = [byte[]](Get-Content C:\admin\User1.jpg -Encoding byte)
Set-ADUser User1 -Replace @{thumbnailPhoto=$UserPhoto}

You can use a software called ADPhotoEdit:

- Image file size should be not higher than 10kb, because with every file you AD database will grow!
- The maximum image size is 100kb
- Pixel size 96x96 pixels is recommended
