      .SYNOPSIS
      Uses Windows lock screen wallpapers to query Google Image Search.
 
      .DESCRIPTION
      The Search-WindowsLockScreenWallpapers cmdlet reads the Windows lock screen wallpapers and uses them to query Google Image Search. This cmdlet can be piped to the Get-ChildItem cmdlet for a batch processing.
 
      .PARAMETER NumberOfImages
      Specifies a number of the latest wallpaper that will be search. The input must be a valid positive number. A default value is 5.
 
      .PARAMETER DumpFiles
      Specifies a switch if wallpaper images should be dumped or not. A default value is False.
 
      .PARAMETER DumpPath
      Specifies a Path to a folder where the wallpapers should be dumped. The input can be a string or a valid instance of the System.IO.FileInfo class. A default value is 'C:\Temp'. The input directory is created if doesn't exist.
 
      .EXAMPLE
      Search-WindowsLockScreenWallpapers
      Search of the five latest downloaded wallpaper images in Google Image Search. It will open five or less tabs in the default web browser.
 
      .EXAMPLE
      Search-WindowsLockScreenWallpapers -DumpFiles
      Search of the five latest downloaded wallpaper images in Google Image Search. It will open five or less tabs in the default web browser. The wallpaper images will be dumped into C:\Temp directory.
 
      .EXAMPLE
      Search-WindowsLockScreenWallpapers -DumpFiles -DumpPath D:\Temp
      Search of the five latest downloaded wallpaper images in Google Image Search. It will open five or less tabs in the default web browser. The wallpaper images will be dumped into custom D:\Temp directory. The input directory is created if doesn't exist.
 
      .EXAMPLE
      Search-WindowsLockScreenWallpapers -NumberOfImages 2 -DumpFiles -DumpPath D:\Temp
      Search of the two latest downloaded wallpaper images in Google Image Search. It will open five or less tabs in the default web browser. The wallpaper images will be dumped into custom D:\Temp directory. The input directory is created if doesn't exist.
 
      .NOTES
      - This cmdlet uses non-standard way how to query Google Image Search. Do not use it for automatization.
      - A dump Path is created if it doesn't exist.
