How to Change Logo in SharePoint 2010 Site
When we create SharePoint sites, it comes with a default logo image from: /_layouts/images/siteIcon.png(SharePoint applies this logo when LogoURL property is empty!) .We can change it to reflect our own branding, so that it can be easily recognized. I needed to apply new logo for all SharePoint sites during a corporate re-branding project.

Instead of manual way, I want to do this change with PowerShell script to update all site collection's Logo icons. Here is my quick PowerShell script to apply and verify the logo for all SharePoint sites:

#Get the Site
$web = Get-SPWeb "http://your-sharepoint-site.com"

#Set Site Logo Icon
$web.SiteLogoUrl = "http://your-sharepoint-site.com/SiteAssets/Corp-logo.png"

#Set Logo Description
$web.SiteLogoDescription = "Corporate Logo for Your Company"

#Update the changes
$web.Update()

Logo can be from any SharePoint Library (such as Assets Library), Make sure all users have read access to the Logo file. Or it can be from 14 Hive's Images Folder (Recommended!) "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\IMAGES".Once uploaded, We can refer it by providing URL: /_layouts/images/YourLogo.png

Important: When you place Logo Inside Images folder, Make sure its inheriting security (Go to Logo file's Properties >> Security >> Advanced >> Make sure "Include Inheritable Permissions from this object's Parent" is selected. If not, Click on "Change Permissions" button and enable "Include Inheritable Permissions from this object's Parent")! otherwise, End-users may get Log-on prompts and page may stop loading.

To Get Logo Information of entire web application:

Get-SPWebApplication "http://your-sharepoint-URL.com" | Get-SPSite | Get-SPWeb | 
 foreach { "Site "+ $_.Url + " Logo URL: " +  $_.SiteLogoUrl }

To Change Logo For All Sites in a Web Application:

Get-SPWebApplication "http://your-sharepoint-URL.com" | Get-SPSite | Get-SPWeb | 
  foreach { $_.SiteLogoUrl = "/_layouts/Images/Corp-Logo.png"; $_.Update() }

To Change Logo for All sites in a Site Collection:

Get-SPSite "http://your-sharepoint-URL.com" | Get-SPWeb | 
   foreach { $_.SiteLogoUrl = "/_layouts/Images/Corp-Logo.png"; $_.Update() }

Ideally, Its a best practice to apply Logos as part of Branding.
