Hi,
I need to change a logo across all of the sites/sub-sites and pages. How can I do that in SharePoint? or do I need to do it with PowerShell script? If yes, can anyone give me a scripts for that?
Thanks in advance.
You absolutely can by using PowerShell. Get a reference to the web application and loop through all of your sites. Here is a link to describe how to do it. http://www.sharepointdiary.com/2014/04/sharepoint-2013-change-site-logo-programmatically-with-powershell.html
