Importing Multiple Images as One Multi-Page Asset

You may group together images and upload them to Hub as a single multi-page asset, where each page is one of the images uploaded.

You may upload such multi-image assets using the Cloud Import method outlined below.

Uploading Multi-Image Assets

Prepare a JSON like the following, where each URL points to an image you'd like to include in the asset. The order of the URLs will determine the order in which images will be presented to the annotator as pages.

While there is no hard limit, we strongly recommend limiting the number of images in a single dataset to 100 or lower.

The following JSON will import two assets of four images each:

[
  {
    "externalId": "my-asset-external-id-1",
    "dataset": [
      "https://url.com/65c18c8b-4513-4a0a-b876-1aeb2e0908ec.png",
      "https://url.com/b0b70590-e4cc-42ef-8537-3ee3f7917fed.jpg",
      "https://url.com/38e11364-1ce0-417a-9e38-436468c555ce.jpg",
      "https://url.com/eff59355-03bd-447f-aa47-46028f90c2e6.jpg"
    ]
  },
  {
    "externalId": "my-asset-external-id-2",
    "dataset": [
      "https://url.com/65c18c8b-4513-4a0a-b876-123456789012.png",
      "https://url.com/b0b70590-e4cc-42ef-8537-234456566787.jpg",
      "https://url.com/38e11364-1ce0-417a-9e38-876345383488.jpg",
      "https://url.com/eff59355-03bd-447f-aa47-319485019239.jpg"
    ]
  }
]

From your project dashboard, go to the Assets tab and click on Add Data. Then, enter the Upload Data URL section and drag and drop your JSON on the file upload field. Then, press on Upload. Your multi-image asset(s) will be uploaded.

Assets uploaded this way will have a slider at the top, allowing annotators to navigate between the images in the dataset.
