To upload images to One3D, click on "Click or drag files to upload" and select a single folder with all your files. A preview of all selected files will appear shortly – here you can select files to be removed or add additional ones. Once all files have been selected, name the asset in the top right field of the main view. On the top right, you can check if your account is eligible for a free trial (active for your first upload of up to 2500 images). To complete the upload, click on "Upload" at the bottom left corner. A loading bar at the bottom will appear and indicate once the upload has finished.
