NEC SV9100 Bulk Photo Upload

On our new SV9100 system we needed a way to bulk upload user thumbnails for their extensions to appear on the new colour screen ITK phones. NEC does not appears to have any way to do this so I have written the following script.

It requires a folder containing your images with the filename ending in the extension it should be uploaded to. This works best if you pre-crop your images to square or similar as on phone the image will be cropped.

Bulk upload extension photos to SV9100
Script to upload photos based on extension number to NEC SV9100 PABX, or perform other bulk individual operations
Photo can be checked at "http://<IP>/UserImages/000.jpg" where number is port – 1
Image names must have extension as last part of name e.g. "Name 122.jpg"
Update stored directory of photos below
Enter the password for a User1 level user.
