// Example code snippet showing how to optimize image processing script using GDlib functions in PHP

// 1. Reduce unnecessary image processing operations
// Only perform the necessary image processing operations to avoid unnecessary overhead
// Avoid repetitive or redundant processing steps

// Save processed images to a cache directory and check if the processed image already exists before reprocessing

// 3. Ensure server resources are sufficient
// Make sure the server running the script has enough memory and processing power to handle image processing tasks efficiently
// Consider optimizing server settings or upgrading server resources if necessary
