After a recent third party migration my logo has disappeared from almost all of my sites and subsites. I have reapplied the themes/masterpages across these sites, but they are still looking for an image that doesn’t exist in the new SP2013 I am using. How do I change it to where all of the sites look for my image instead of going site by site and changing it?
SP2007 had the following image that 2013 is looking for: /_layouts/images/WCT_Logo.jpg
I want it to be looking here: /SiteAssets/Knight_Head.jpg
Oh, I think I missed that it was the site logo. You could go to each site and change it in the site settings. You could also use PowerShell to set them all pretty quickly. This link has a script to do so: Set Logos on all SharePoint Sites in a Site Collection – PowerShell One-liner
