Virtual booths

  • Carousel section
    • Images can be uploaded and added as a link. The recommended file size is 16:9 in png, jpg, jpeg, or gif format. It's recommended images of 737x600px; however, note that the image in the iframe will adapt to your screen size and port.
    • If you add an image with an URL, it could be bigger in size as it will adapt accordingly, thanks to the iframe. Here you can watch how pictures and other materials look in the carousel section.
  • Sidebar section

🚨 Note! If you come across issues regarding image sizing or other materials, go to find solutions for virtual booth material errors.
