Make sure to fill out "Name" and "Subject" as it's a requirement.

Select the photo icon to add a picture.

Adjust the picture size

Quick tip: Set a width of 150-260px for logos, that looks great on most screen, 100% width for full screen images, you rarely need to set the height as the image should also scale

Enter any "Variables" you require

Then Click on "Save" on the bottom right corner of the page.
