Step by Step:

#1 To add a logo you must place the logo on your server in a shared drive that ALL users have access to. 

 - It cannot be placed in a local drive, such as C: or D: There is usually an Evosus shared drive which should work. Essentially, everyone needs to be able to access whatever drive the logo is saved in. 

#2 Logo should be a 300dpi jpg file.  This will allow the file to be resized in Evosus without losing resolution. 

#3 Once the logo is saved, go to Administration > System> Stores > Stores > Select the Store > Go to the Logos tab. 

#4 Browse to the folder where the logo is located and select the logo. 

#5 Click OK to save.
