This code uses card images (except for the badges). So to edit the images, look for the "background-image" tag and replace the url

eg: background-image:url(https://via.placeholder.com/250px) - replace https://via.placeholder.com/250px with the link to the pic you want

for adjusting I have a guide for that here: https://toyhou.se/11235695.-guide-card-images . hope this helps!
