How can one troubleshoot and debug issues with image display in different browsers when using PHP scripts?

One common issue with image display in different browsers when using PHP scripts is incorrect image MIME type or encoding. To troubleshoot this, check if the image MIME type is set correctly in the PHP script using the header() function. Additionally, ensure that the image encoding is handled properly to avoid display issues.

// Set the correct MIME type for the image
header('Content-Type: image/jpeg');

// Output the image content
readfile('path/to/image.jpg');
