Current landing page image settings
Go to Settings > Form Settings > Landing Page.
On the Landing Page card, select "Edit", then open "General Settings".
For the background photo, select "Click to upload" next to "Main Image" and choose your image. Use "Logo Left" or "Logo Right" for each logo that you need.
Select "Save Changes".
The Main Image accepts JPG, JPEG, and PNG files. The application keeps each image edge within 2,000 pixels. There is no fixed image width or height.
What it does not do
The Main Image field only accepts a photo file (JPG, JPEG or PNG). There is no colour picker on this panel, so you cannot replace the background photo with a plain colour from here.
If your school wants a plain colour background instead of a photo, contact Applicaa support to ask what is possible for your account.
