This picture below is actually generated on the fly by php
If you wish to do the same then use the normal html IMG tage with the SRC pointing to a php page.
In the php page put the code to generate a picture
It shows a black image of 600 x 30 pixels, with the time and date overlayed as a string

PHP Code to generate the above:

Normal HTML code to display an image: <img src="picture.jpg">
Change the image source to point to a php file : <img src="picture.php">

Contents of picture.php file:
<?php
// Inform the browser what type of file this is i.e. image as png format
header ('Content-Type: image/png');
// Set the default timezone used by all date/time functions in a script
date_default_timezone_set('Europe/Dublin');
// allocate memory for the image
$im = @imagecreatetruecolor(410, 80)
    or die('Cannot Initialize new GD image stream');
// define a background colour to use
$background_color = imagecolorallocate($im, 0, 0, 0);
// define a text colour to use
$text_color = imagecolorallocate($im, 14, 233, 91);
// the text to display, in this case the current time
$datestring = date('l jS \of F Y h:i:s A');
// place the text on the image
imagestring($im, 5, 10, 10,  $datestring, $text_color);
// convert bitmap image to png
imagepng($im);
// release local resources
imagedestroy($im);
