When you sign up for a Litmos trial account you can select a logo to upload or you can skip the logo and upload it later on.
To upload or change your logo in your Litmos account, go to the Account section and select the Theme tab.
The recommended size for your logo is a maximum of:
90px high x 300px wide
If the logo you upload is greater than the recommended size it will be automatically scaled down.
We covered this in our Account: Theme course, check it out in Litmos Dojo!
