4. Create “c:\SPSolutions\ImportProfileImages\RunUpdateUserProfiles.ps1” with this code:

   cd C:\SPSolutions\ImportProfilePhotos. .\UpdateProfiles.ps1Update-SPProfilePictures "http://my-sites-host-url" "User Photos" "c:\SPSolutions\ImportProfileImages\ProfileImages" "Your_Domain"

5. Save the files, copy images into the “ProfileImages” folder, using the useralias as filename.
6. Rightclick “RunUpdateUserProfiles.ps1” and select “Run with PowerShell”
