Azure – Get-AzVMImage doesnt output PSVirtualMachineImageDetail

Im trying to fetch the detailed information from a azure VM Image but the information doesnt seem to be there.

$location = "swedencentral"
$publisher = "MicrosoftSQLServer" 

#Get all offers for selected publisher
$Alloffers = @(Get-AzVMImageOffer -Location $location -PublisherName $publisher | Select-Object -ExpandProperty Offer)

#Get all images for all skus of all ofers for the selected publisher
foreach ($Offer in $Alloffers) {
    $Allskus = (Get-AzVMImageSku -Location $location -PublisherName $publisher -Offer $offer | Select-Object  -ExpandProperty Skus)
    
    foreach ($sku in $Allskus) {
        $images += @(Get-AzVMImage -Location $location -PublisherName $publisher -Offer $offer -Skus $sku -Version latest)
     }
}

$images

According to documentation Get-AzVMImage should output PSVirtualMachineImage and PSVirtualMachineImageDetail but the result suggest that only PSVirtualMachineImage is outputed.

https://learn.microsoft.com/en-us/powershell/module/az.compute/get-azvmimage?view=azps-11.1.0

Im I missing something or how can I with PowerShell get the detailed information from an Azure VM Image, specifically I want the Name and the OSDiskImage information.

    When using -Version latest, I notice that only partial details are returned for the image.

    When using a specific version Id, more details are returned. Here is example output:

    $temp = Get-AzVMImage -Location $location -PublisherName $publisher -Offer $offer -Skus $sku -Version latest
$imageFullDetails = Get-AzVMImage -Location $location -PublisherName $publisher -Offer $offer -Skus $sku -Version $temp.Version

    Full output:

    PS C:WINDOWSsystem32> $temp = Get-AzVMImage -Location $location -PublisherName $publisher -Offer $offer -Skus $sku -Version latest
PS C:WINDOWSsystem32> $temp

    I tired to use Get-AzVMImage to fetch PSVirtualMachineImageDetail and I was able to provision the requirement successfully.

    The Get-AzVMImage command does not produce the expected output. You want to see a PSVirtualMachineImageDetail object that contains detailed information, such as the Name and OSDiskImage, of the virtual machine image.

    The Get-AzVMImage cmdlet is indeed supposed to return objects of type PSVirtualMachineImage and PSVirtualMachineImageDetail, as per the documentation. The PSVirtualMachineImageDetail object contains detailed information about the VM image, including properties like OSDiskImage.

    PowerShell output can be very verbose and hide the details you need. Inspect the output carefully.

    Powershell script:

    $images = Get-AzImage

if ($images -ne $null) {
    foreach ($image in $images) {
        $output = New-Object PSObject -Property @{
            Name = $image.Name
            ResourceGroupName = $image.ResourceGroupName
            Location = $image.Location
            OSDiskImage = $image.StorageProfile.OsDisk
            DataDisks = $image.StorageProfile.DataDisks | ForEach-Object {
                @{
                    Lun = $_.Lun
                    BlobUri = $_.BlobUri
                    Caching = $_.Caching
                    SizeGB = $_.DiskSizeGB
                }
            }
            Tags = $image.Tags
        }
        $output | Format-List
    }
} else {
    Write-Host "No images found in the subscription."
}

    Output:
