Upload file from custom binary attribute to SharePoint

Question

I'm trying to do something very similar to:

https://www.adaxes.com/questions/10758/copy-image-uploaded-binary-custom-attribute-network-share

but rather than uploading the M365, uploading to a specific SharePoint folder with the photo file named as the user account's sAMAccountName.

If I could save the photo as an image file I could then use PnP.PowerShell to upload it, but I'm stuck on this step.

I have Adaxes version 3.16.21627.0

Hello,

The approach will be the same, where you will need to save a picture to a custom Binary attribute. In the script, you will use the below code to obtain the attribute value and then you can proceed with saving it to a SharePoint folder as a file.

$copyFromPropertyName = "adm-CustomAttributeBinary1" # TODO: modify me

# Get the picture
try
{
    $photoBytes = $Context.TargetObject.Get($copyFromPropertyName)
}
catch
{
    $Context.LogMessage("No picture specified in attribute $copyFromPropertyName.", "Warning")
    return # No picture
}

Unfortunately, we do not have any scripts for saving the contents of a Binary attribtue to a file, but the following thread might be helpful: https://stackoverflow.com/questions/926935/rails-saving-the-contents-of-a-binary-field-to-a-file.
