Insert Image on top navigation bar

I’ve updated OJS 2.4 to 3.0.2 but I need to insert an image in the top bar navigation similar as it is done via back-end configuration page in version 2.4. How can I proceed?
Thank you!

Hi @Leandro_Coutinho

Have you search this forum if the answer to your problem already exist?

You can upload an image as journal manager, under Settings > Website > Appearance > Logo.

Best,
