Photo Renamer Tool

A simple yet powerful batch utility to sequentially rename photo files in a folder from 1 to N.

📷 Overview

Photo Renamer Tool automatically renames all image files in a folder with sequential numbers (1.jpg, 2.jpg, 3.jpg, etc.), making it easier to organize and sort your photo collection.

✨ Features

• Sequentially renames all photos in a folder (1, 2, 3, etc.)
• Supports multiple image formats (JPG, PNG, JPEG) in both lowercase and uppercase
• Uses a two-pass system to ensure no file conflicts during renaming
• Simple user interface with progress feedback
• No installation required - just a single batch file

🚀 Usage

1. Place the photo-renamer-tool.bat file in the folder containing your photos
2. Double-click the batch file to run it
3. All photos will be renamed sequentially starting from 1

🔒 Security Notes

Windows may display a security warning when running this batch file as it's not signed by a recognized certificate authority. This is normal for any script downloaded from the internet.

To reduce security warnings, you can:

Option 1 (Simple)

• Right-click the batch file
• Choose "Properties"
• Check the "Unblock" box (if present)
• Click "OK"

Option 2 (Advanced - requires administrator privileges)

• Right-click on sign-script.ps1
• Choose "Run with PowerShell as Administrator"
• This will create a self-signed certificate and sign the batch file

📋 How It Works

The script works in two phases:

1. First pass: All image files are renamed to temporary names (temp_1000000.jpg, etc.) to avoid conflicts
2. Second pass: The temporary files are renamed to their final sequential numbers (1.jpg, 2.jpg, etc.)
