Image export

Availability and destinations

Image export is available on the Scale plan and requires at least one Image selector in the sitemap.

Supported image-storage destinations are:

  • Amazon S3
  • Google Cloud Storage
  • Microsoft Azure Blob Storage

How Image export works

Images are downloaded during scraping as Image selectors return image URLs. This differs from normal Data Export, which sends the completed dataset after the scraping job finishes.

  1. Validate the Image selector.
  2. Configure Data Export to a supported storage destination.
  3. Open the sitemap's Image export tab and enable Image export.
  4. Run a job and verify the exported data and image files.

Image location and filenames

Images are stored in an images subfolder under the configured export path.

product-catalog/
├── data.csv
└── images/
    ├── 4d8f...jpg
    └── 83a1...png

Stored filenames are generated from the SHA-256 hash of the image URL. The exported dataset keeps the Image-selector value and adds a stored-filename column using:

{selector_id}_stored_filename

For an Image selector named product_image, the additional column is product_image_stored_filename.

Output by Multiple type

Multiple type Output
First Record Only product_image and product_image_stored_filename
Multiple Records in Multiple Columns Each image gets a numbered URL column and matching stored-filename column, for example product_image_1 and product_image_1_stored_filename.
Multiple Records in One Column Uses product_image and product_image_stored_filename; multiple stored filenames are separated by line breaks.

Keep the Image selector's Multiple type stable if downstream systems depend on a fixed exported schema.

Validate the export

Confirm that the dataset contains the expected _stored_filename field, that the corresponding files exist in the images folder, and that each stored file maps to the image URL in the same record.

Troubleshooting

Image export tab is not visible

Confirm that the sitemap contains an Image selector and that the account is on Scale.

Data exported but no image files are present

Confirm that Image export is enabled for a supported storage destination and that the Image selector returned image values.

Unexpected image columns

Check the Image selector's Multiple type; each option produces a different output structure.
