Automatic Wallpaper Downloader

Are you tired of boring wallpapers for your desktop? PowerShell can get you new wallpapers! Here’s the function:

function Download-Wallpaper
{
    param
    (
        [string]
        [Parameter(Mandatory)]
        $Folder,
 
        [Parameter(ValueFromPipeline)]
        [Int]
        $Page=1
    )
    
    begin
    {
        $url = "http://wallpaperswide.com/page/$Page"
        $targetExists = Test-Path -Path $Folder
        if (!$targetExists) { $null = New-Item -Path $Folder -ItemType Directory }
    }
    process
    {
        $web = Invoke-WebRequest -Uri $url -UseBasicParsing
 
        $web.Images.src | 
        ForEach-Object {
    
            $filename = $_.Split('/')[-1].Replace('t1.jpg','wallpaper-5120x3200.jpg')
            $source = "http://wallpaperswide.com/download/$filename"
    
            $TargetPath = Join-Path -Path $folder -ChildPath $filename
 
            Invoke-WebRequest -Uri $source -OutFile $TargetPath
        }
    }
    end
    {
        explorer $Folder
    }
}

And this is how you can use it:

 
PS> Download-Wallpaper -Folder c:\wallpapers

It downloads all wallpapers from a public wallpaper website to a local folder, then opens the folder. All you need to do is right-click the wallpaper of choice and choose “Set as Desktop Background”.

By default, Download-Wallpaper downloads the wallpapers from the first page. With the -Page parameter, you can scrape wallpapers from additional pages. Try this:

 
PS> Download-Wallpaper -Folder c:\wallpapers
