Build a batch photo renamer

Here’s a simple yet functional batch photo renamer in Python. It allows you to rename all images in a folder according to a pattern you define, like Vacation_001.jpg, Vacation_002.jpg, and so on.

🔧 Features:

• Works with .jpg, .jpeg, .png, .gif, and .bmp by default

• Allows customizable base name

• Numbers files sequentially with optional padding

• Skips non-image files

🐍 Python Script: Batch Photo Renamer

python
CopyEdit
import os

def batch_rename_photos(
    folder_path, 
    base_name="Image", 
    start_index=1, 
    padding=3, 
    extensions=(".jpg", ".jpeg", ".png", ".gif", ".bmp")
):
    if not os.path.isdir(folder_path):
        print(f"Error: '{folder_path}' is not a valid directory.")
        return

    photos = [f for f in os.listdir(folder_path) if f.lower().endswith(extensions)]
    photos.sort()  # Ensures consistent order

    if not photos:
        print("No image files found in the specified directory.")
        return

    print(f"Renaming {len(photos)} files...")

    for i, filename in enumerate(photos, start=start_index):
        ext = os.path.splitext(filename)[1]
        new_name = f"{base_name}_{str(i).zfill(padding)}{ext}"
        src = os.path.join(folder_path, filename)
        dst = os.path.join(folder_path, new_name)

        try:
            os.rename(src, dst)
            print(f"Renamed: {filename} → {new_name}")
        except Exception as e:
            print(f"Failed to rename {filename}: {e}")

    print("Batch renaming completed.")

# Example usage:
if __name__ == "__main__":
    folder = input("Enter the path to the folder: ")
    base = input("Enter base name for files (default: Image): ") or "Image"
    try:
        start = int(input("Enter starting index (default: 1): ") or "1")
        pad = int(input("Enter zero padding length (default: 3): ") or "3")
    except ValueError:
        print("Invalid input for index or padding. Using defaults.")
        start, pad = 1, 3

    batch_rename_photos(folder, base, start, pad)

🧪 How to Use:

1. Save this code as batch_renamer.py.

2. Run it with Python:

   bash
   CopyEdit
   python batch_renamer.py
   

3. Enter the directory containing the images and follow the prompts.

Would you like a GUI version using tkinter, or a command-line only tool with extra options (e.g., dry run, undo, regex matching)?
