Image Resizer Script

This Python script helps reduce the disk space used by images. It scans all directories and subdirectories starting from the current directory, finds image files (.png, .jpg, .jpeg, .bmp), and resizes them, saving the smaller versions in a backup directory. The original images are not altered.

Features

• Scans all directories and subdirectories from the current directory.
• Resizes images (PNG, JPG, JPEG, BMP) to save disk space.
• Creates a backup directory that mirrors the existing directory structure.
• Skips images that are already small (width <= 1024px, height <= 768px, file size <= 50KB).
• Handles errors gracefully, ensuring the script continues running even if some images cannot be processed.
• Displays a progress bar indicating the number of processed files and the total disk space saved by reducing image sizes.

Important Considerations

• The script counts the total number of image files in the directory first, and then walks the directory again to process each image. This is fine for small directories, but for large directories with millions of files, this could take a considerable amount of time before the actual processing begins.
• The script converts all images, regardless of the original format (PNG, BMP, JPEG), to JPEG. This may lead to loss of quality in certain images, particularly PNGs with transparency, which JPEG does not support.

Usage

1. Clone this repository or download the IMGbackup.py script.
2. Place the script in the directory where you want to start the scan.
3. Run the script using Python: python IMGbackup.py.

Requirements

This script requires Python 3 and the following Python packages:

• Pillow for handling image operations.
• tqdm for displaying progress information.

You can install these packages using pip:

pip install pillow tqdm
