How can developers effectively troubleshoot and debug image conversion scripts in PHP to ensure proper functionality?

Issue: To effectively troubleshoot and debug image conversion scripts in PHP, developers can use error logging, var_dump or print_r functions to inspect variables, and step through the code using breakpoints in an IDE. 

// Example code snippet for debugging image conversion script in PHP

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Set up error logging
ini_set('log_errors', 1);
ini_set('error_log', 'error.log');

// Debugging output
var_dump($variable_to_inspect);
print_r($array_to_inspect);

// Breakpoints in IDE for step-by-step debugging
// Use a debugger like Xdebug for more advanced debugging capabilities
