Hi @roshaan,

As explained on the “Images” section of the “Problem Description” page, the images must be downloaded from S3. We provide the URLs to the images in the CSV files you downloaded so that you can get just the ones you need from AWS. The entire dataset is incredibly large (multiple TBs) so you probably don’t want to just download the raw version of everything. Here’s the information:

> **[TissueNet: Detect Lesions in Cervical Biopsies](https://www.drivendata.org/competitions/67/competition-cervical-biopsy/page/255/#images)**
>
> The objective of this challenge is to detect the most severe epithelial lesions of the uterine cervix. The challenge brings together thousands of microscopic slides from different medical centers across France.

As mentioned, you can use the AWS CLI tool to download the image files from S3.
