.SYNOPSIS | |
Create a new desktop wallpaper from various sources and optionally overlay some text. | |
.DESCRIPTION | |
The script can be run manually, at logon or even as a scheduled task to update the wallpaper regularly | |
Wallpaper sources include: | |
- A solid colour | |
- A specific or random picture from a directory | |
- An Internet search (via Google images). | |
Text overlay options include: | |
- Font, colour, size and placement. | |
.USAGE | |
Shell Syntax | |
Set-Wallpaper [[-Source] <Colour/MyPics/Web>] [[-Selection] <string>] | |
Colour Example | |
.\Set-Wallpaper.ps1 Colour Blue | |
MyPics Examples | |
.\Set-Wallpaper.ps1 MyPics * | |
.\Set-Wallpaper.ps1 MyPics coolpic.jpg | |
Web Example | |
.\Set-Wallpaper.ps1 Web 'Ayers Rock' | |
NB. Powershell v3 or later required for 'Web' (invoke-webrequest cmdlet) | |
Running at Logon | |
Create a shortcut (in your Startup folder), with the following target syntax | |
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -noexit ".'"c:\MyScripts\Set-Wallpaper.ps1 Colour Blue'" | |
Running as a (background) scheduled task | |
Typically Powershell will popup a small window, even if you select the 'WindowsStyle Hidden' and 'nologo' options. | |
An easy work around for this is to create a set-wallpaper.vbs file containing the powershell arguments like the following example: | |
Dim shell,command | |
command = "powershell.exe -nologo -command ""C:\MyScripts\Set-wallpaper.ps1 Colour Blue""" | |
Set shell = CreateObject("WScript.Shell") | |
shell.Run command,0 | |
Then point your scheduled task to run the .vbs file as required | |
Start a program: C:\MyScripts\Set-Wallpaper.vbs | |
Start in: c:\MyScripts\ | |
.SETUP VARIABLES | |
There are a number of setup variables that should be reviewed and updated as required in the "Wallpaper Vartiables" section below | |
# MyPics Options | |
$PicturesPath [URL] Pictures can be sourced from a local or shared drive (Default is 'My Pictures') | |
$ResizeMyPics [$True/False] Large images can be resized to match screen resolution (which makes the layout and any text overlays look better). | |
!! Use $ResizeMyPics with caution !! ALL pictures in selcted folder (with a higher resolution than the screen hight or width) will be resized automatically | |
# Web Options | |
$WebProxyServer [STRING] Enter proxy server name if required for the web search | |
$MaxResults [INT] Specify the maximum number of images to download | |
$DaysBetweenSearches [INT] This period allows the script to re-run for wallpaper updates without re-downloading pictures on every pass | |
$ResizeWebPics [$True/$False] Once downloaded, large images can be automatically resized to match screen resolution (which makes the layout and any text overlays look better). | |
!! Use $ResizeWebPics with caution !! ALL pictures in selcted folder (with a higher resolution than the screen hight or width) will be resized automatically | |
NB. When sourcing from the web, tiny images will automatically be removed (usually means a failed download) | |
# Text overlay options | |
$TextOverlay [$True/$False] Toggle a text overlay on the background image | |
$TextColour [STRING] Font Colour | |
$FontName [STRING] Font Name | |
$FontSize [INT] Font Size (9 - 42) | |
$ApplyHeader [$True/$False] Makes the first line a header (bigger and bold) | |
$TextAlign [STRING] Text allignment on screen: 'Center', 'Left' or 'Right' | |
$Position [STRING] Text placement on screen: 'High' or 'Low' | |
NB. Update the 'Build-TextOverlay' function to change the actual information displayed | |
eg $Computer = $env:COMPUTERNAME | |
$UserName = '{0}\{1}' -f $env:USERDOMAIN,$env:USERNAME | |
$ip = get-WmiObject Win32_NetworkAdapterConfiguration | Where {$_.Ipaddress.length -gt 1} | |
$oText = @" | |
Computer: $env:COMPUTERNAME | |
Username: $UserName | |
IP Address: $($ip.ipaddress[0]) | |
"@ | |
# Wallpaper Style options | |
$Style [STRING] 'Center','Stretch','Fill','Tile' or'Fit' | |
# Colour Options | |
1. More background and text colours can be addeded to the functions by specifying a Name and corresponding RGB value | |
eg Update Wallpaper variables | |
$CornflourBlue = @(100,149,237) | |
NB. Also ensure to update the 'New-wallpaper' function with any new colours | |
Switch ($BGColour) { | |
CornflourBlue {$BG = $CornflourBlue} | |
} | |
Switch ($TextColour) { | |
CornflourBlue {$TColour = $CornflourBlue} | |
} | |
NB. Solid colour backgrounds are actually rectangles drawn at the native screen resultion and will be applied immediately. | |
A background colour will also be set (may show as a border around MyPics or Web selections), but this will not apply until next login | |
