You can upload your shelter or rescue's logo by navigating to Configuration (General Shelter > My Organization > Shelter Logo). Be sure to scroll down and click "Update" to save the change before navigating away from the page. 

Your uploaded logo will display on your main home screen of Shelterluv and on your kennel card (if you've chosen a template that includes your logo).

Only users with configuration permissions will have access to the Configuration page to make these types of changes with the logo.
