Bild in Powershell GUI löschen

Guten Abend, Ich möchte diese Bild löschen. Ich habe bereits die Variable als Global festzulegen und das Bild über:

$Uebersicht.Controls.Remove($pictureBox1)
zu löschen oder über:

$pictureBox1.Dispose()

Das Bild ist leider sehr hartnäckig und lässt sich nicht löschen, weiß jemand wieso? o.O

 
        $pictureBox1 = New-Object System.Windows.Forms.PictureBox
        $pictureBox1.Size = New-Object System.Drawing.Size(300,200)
        $pictureBox1.Location = New-Object System.Drawing.Point(300,50)
        $Uebersicht.Controls.Add($pictureBox1)
        $image1 = [System.Drawing.Image]::FromFile("C:\Users\Administrator\Desktop\images(2).png")  
        $pictureBox1.Image = $image1
