Not able to get Image ID of existence ec2 instance from powershell

I am trying to get the spowershell script so that I can pull up the image id of existence ec2 instance.

like : 

Write-Host -BackgroundColor White -ForegroundColor Blue "What is the ID of the instance"
$tid=Read-Host "Instance ID"
Write-Host -BackgroundColor White -ForegroundColor Blue "Input the region the instance inhabits"
$tregion=Read-Host "Region"
$Tinstancetype = ((Get-EC2Instance -InstanceId $tid).instances).InstanceType
Write-Host "Instance Type : $Tinstancetype"

Like in this code above, I entered Instance id and it spill out instance type. I need the code which can spill out Image ID.

You are only requesting the Instance Type property. Get-EC2Instance will bring back an array of objects, each object has a number of properties. your command is only displaying the value of the property `InstanceType'

If you run (Get-EC2Instance -InstanceId $tid).instances | Select * you will see all the properties and their values, one of those properties will be image ID.

Example of Get-EC2Instance output:

C:\> (Get-EC2Instance -InstanceId i-12345678).Instances

VirtualizationType    : hvm
VpcId                 : vpc-12345678

Your script will look something like this:

Write-Host -BackgroundColor White -ForegroundColor Blue "What is the ID of the instance"
$tid=Read-Host "Instance ID"
Write-Host -BackgroundColor White -ForegroundColor Blue "Input the region the instance inhabits"
$tregion=Read-Host "Region"
$Instance = ((Get-EC2Instance -InstanceId $tid).instances)
$Tinstancetype = $Instance.InstanceType
$ImageID =$Instance.ImageId
Write-Host "Instance Type : $Tinstancetype"
Write-Host "Instance Type : $ImageID"
