Are there any specific best practices for handling temporary image files in PHP scripts?

When working with temporary image files in PHP scripts, it is important to ensure that these files are properly handled and cleaned up to avoid cluttering the server with unnecessary files. One best practice is to use PHP's `tempnam()` function to create a unique temporary file name and store the image data in that file. After processing the image, remember to delete the temporary file to free up server resources. 

// Create a temporary file for storing image data
$tempFile = tempnam(sys_get_temp_dir(), 'image');

// Write image data to the temporary file
file_put_contents($tempFile, $imageData);

// Process the image...

// Delete the temporary file after processing
unlink($tempFile);
