How to replace images of 'The Galleries' in Charity - Nonprofit, Fundraising Joomla Template

Hi Team! I have purchased [Charity - Nonprofit, Fundraising Joomla Template], While performing the basic editing, replacing the images on the default homepage under SPpageBuilder menu for Frontend editing. It shows no images rather the categories for The Galleries section. I tried finding the module, related components and plugins but none shows the option to replace these default images.
Kindly help me understand - “How to replace all the images under various sections inclusing the Galleries section too?”
I shall appreciate your quick response.
Thanks
