Downloading Images

Once you have the URLs or S3 file keys from the metadata files, you can download the images through any standard means.

cURL

Download an image from a url to a local image file with the name image.png:

curl -O image.png https://pd12m.s3.us-west-2.amazonaws.com/images/image.png

Python

Download an image from a url to a local image file with the name image.png:

import requests

url = "https://pd12m.s3.us-west-2.amazonaws.com/images/image.png"
response = requests.get(url)
with open('image.png', 'wb') as f:
    f.write(response.content)

img2dataset

You can also use the img2dataset tool to quickly download images from a metadata file. The tool is available here. The example below will download all the images to a local images directory.

img2dataset download --url_list pd12m.01.parquet --input_format parquet --url_col url --caption_col caption --output-dir images/
