What are common pitfalls when trying to display an image in a browser using PHP?

Common pitfalls when trying to display an image in a browser using PHP include not setting the correct Content-Type header, not reading the image file correctly, and not outputting the image data properly. To solve this, make sure to set the Content-Type header to the correct image type (e.g. image/jpeg, image/png), read the image file using functions like file_get_contents(), and output the image data using echo or fwrite(). 

<?php
// Set the Content-Type header
header('Content-Type: image/jpeg');

// Read the image file
$image = file_get_contents('path/to/image.jpg');

// Output the image data
echo $image;
?>
