To begin tagging 360 images you must first upload your image to ThingLink. Click create in the top navigation bar to access the upload page. On the create page, click the second blue button that reads UPLOAD PANORAMIC IMAGE 360. You must have the Premium, Corporate, or School-wide account to access this feature.
Your image must be in JPEG format with 2:1 aspect ratio, and maximum resolution of 5376x2688. Most 360 cameras, including Ricoh Theta and Google Street View App will produce images that fit these requirements. If your image is not the proper resolution this can easily be adjusted on a Mac or PC. On a Mac open the image in preview. Use the Adjust Size option in the Tools menu to meet the size requirements. On PC, open the image in MS Paint and use the Resize button.
