Duplicate Photo Identifier

This project contains a prompt and Python script for creating an HTML report of duplicate and unique photo files.

What the Prompt Does

The prompt in duplicate_photo_report_prompt.md asks a coding assistant to review and improve find_duplicates.py.

It describes a task where the script should:

• Scan a target folder for image files.
• Calculate a SHA256 hash for each photo.
• Group photos with matching hashes as exact duplicates.
• Separate photos that appear only once as unique files.
• Create an HTML report named duplicate_report.html.

Expected HTML Report

The generated HTML file should contain two tables.

Table 1: Duplicates

This table lists every photo that belongs to a duplicate group.

Columns:

• Hash Tag number
• Photo Name
• Photo Size
• Folder

Photos with the same file hash should share the same hash tag number.

Table 2: Unique Files

This table lists photos whose hash appears only once.

Columns:

• Hash Tag number
• Photo Name
• Photo Size
• Folder

Other Prompt Requirements

The prompt also asks that the code:

• Saves the HTML report in the same folder as find_duplicates.py.
• Escapes file names and folder paths before writing them into HTML.
• Formats photo sizes in readable units such as KB, MB, or GB.
• Shows a clear message if either table has no rows.
• Keeps the implementation simple and readable.
• Verifies that the report can be created successfully.
