You prefer the dogs, the cat or the lucky hamster? (refresh to randomize another image)

Code Analysis
In the source code the function

function LoadJpeg($imgname)

takes in input the image name and returns the content of the image.
In the main program through the lone

header("Content-Type: image/jpeg");

I set the header of the page as JPEG. After that I generate a random number and call the function LoadJpeg with a filename like randomNumer.jpg (eg. 2.jpg if we generate the random number 2).

// number from 1 to 3
$random = (rand()%3) + 1;
// random image name
$imgname = "$random.jpg";
// load the image
$img = LoadJpeg($imgname);

Now i call the function imagejpeg that send the image to the browser, passing to it the content of the random image

// sending the image to the browser
imagejpeg($img);
