What are some common methods for converting HEX data to a format that can be displayed as a JPEG image in PHP?

When converting HEX data to a format that can be displayed as a JPEG image in PHP, one common method is to use the `hex2bin()` function to convert the HEX data to binary, and then use the `imagecreatefromstring()` function to create an image resource from the binary data. Finally, you can output the image using the `imagejpeg()` function. 

// Assuming $hexData contains the HEX data
$binaryData = hex2bin($hexData);
$image = imagecreatefromstring($binaryData);

// Output the image as a JPEG
header('Content-Type: image/jpeg');
imagejpeg($image);
imagedestroy($image);
