The placeholder graphics in your PostUP instance‚ including the QR code display, background images, and logo elements‚ can all be replaced through the Design and Image Upload sections in your mainboard settings. Navigate to your instance, go to the mainboard configuration, and look for the uploads section where you can replace any default placeholder images with your own branded assets. For the QR code display graphic, you'll want to download the template image, add your own team logo and branding in Photoshop or similar software, and re-upload it. Make sure you're using the correct QR code that corresponds to your specific instance (found next to the instance name) rather than any placeholder QR codes that may have been included in the default setup. All uploaded graphics should match the specifications listed in the graphic specs guide to ensure proper display.
