Hi:
I am not sure what you mean by "change logo in the servers". If you are using Base SAS and ODS and you want to insert a logo in your ODS results file, then the 2 methods that I outline above are the only methods that I know about.
If, on the other hand, you are talking about using SAS Enterprise Guide, Enterprise Miner, Forecast Studio, JMP, the SAS Add-in for Microsoft Office, Web Report Studio, the SAS Information Delivery Portal or ????? I am not sure how all of those products or solutions or client applications use logos. For example, if you are running SAS Web Report Studio under the SAS Enterprise Intelligence Platform (also known as the BI Platform), you have to register your logos and images in the metadata before they can be used on a WRS report.
Your best resource, at this point, might be to open a track with Tech Support to clarify how to do what you want to do with logos, depending on your SAS configuration and the product where you want to use a logo. To open a track with Tech Support, go to:
