Introduction

This report details information about the ballot image archives provided by the election district. These ballot image archives are typically provided as ZIP archives, but they may also be PDF files with many 1000s of images of sheets in some cases. Here, we review the sizes of the images and whether there are any repeated ballot_ids. This does not examine the images to find repeats, but simply marks them as repeats if they have the same ballot_id. The ballot_id of each ballot sheet must be unique. If there are multiple-sheet ballots, they will have multiple images that are not kept together.
