Adding a logo at the top of a submission form adds a bit of personalisation, colour and legitimacy.
How to Add

Click on Projects to see all your active types.
Select the Project you want to setup a form for and click Submission Form
Select the Appearance option and select Header Image
Add the option to "Change" and select a file from your device and save that in place (PNG or JPEG). This image will then display at the top of the Submission Form. Each Submission Form can have a different image if required.
