+This dataset is a shuffled list of downloadable CC0 image titles and URLs from [Smithsonian Open Access](https://github.com/Smithsonian/OpenAccess), filtered down to ~100k visually-interesting images.
+
+This dataset only contains metadata; a tool like https://github.com/rom1504/img2dataset can be used to download the actual images:
+
+```bash
+img2dataset --url_list data --output_folder data_files \
+   --input_format "parquet" --output_format files \
+   --caption_col "text" --url_col "url" \
+   --image_size 256 --min_image_size 128 --resize_mode keep_ratio --resize_only_if_bigger true \
+   --processes_count 16 --thread_count 128
+```
+
+Here's what a random selection looks like:
