• The image loader was tweaked for preloading and decoding 100MB jpg hdr files over network without any OOM crashes, and smaller files should load instantly.
• Accurate HDR presentation of RAW and JXR images (compared with DaVinci Resolve).

Set-SmbShare -Name "Media" -EncryptData $true
Set-SmbServerConfiguration -RejectUnencryptedAccess $false -Force

while ($true) {
    Clear-Host
    $config = Get-SmbServerConfiguration
    $sessions = Get-SmbSession

    Write-Host "--- SMB SERVER ENCRYPTION STATUS ---" -ForegroundColor Cyan
    Write-Host "Global Server Encryption Enabled : $($config.EncryptData)"
    Write-Host "Reject Unencrypted Access       : $($config.RejectUnencryptedAccess)"
    Write-Host "Active Sessions                 : $(($sessions).Count)"
