Working with image

Hi,
I saw the following in the code of a hit counter.
<img src="http://domain.com/count.php?id=1&type=2">

I think they are calling a php script in a Image tag. Can that be done?
If yes, how will I read the variables "id" and "type"?
Then show a picture...

It's confusing. Can you please help me here?
Thank you

Those are GET variables, so you would access them by $_GET['var_name'].

$id = $_GET['id'];
$type = $_GET['type'];

Making images is pretty simple or pretty challenging depending on what you're doing. Here's a very basic example:

<?php //make sure "<?php" is the [B]first line[/B]. Any whitespace or characters before it will break the script

header('Content-type: Image/png');

$im = imagecreate('200', '200'); //creates a 200 x 200 image

//The first color you define will fill the image. In this case white is fine. Use imagefill() otherwise
$white = imagecolorallocate($im, 255, 255, 255); 
$red = ImageColorAllocate ($im, 192, 0, 0);
$blue = imagecolorallocate($im, 0, 0, 255);

ImageString($im, 3, 5, 5, 'This is a test!', $red); //prints a string on your image

imagepng($im); //This actually outputs your image
imagedestroy($im); //Clears memory and the temp file created (I think)

?>//No trailing whitespace or characters

I cannot express how much amazed I am !!!
For a moment I think my eyes would have popped out...
Thanks so much for introducing me to a whole new set of programming.
Thank you
Best wishes for you.

You will need to have the GD library installed to use the image functions mentioned above.

You can also show an image file with the filesystem functions:

<?php

  header('Content-Type: image/gif');
  $open = @fopen('/path/to/image','r');
  @fpassthru($open);
  @fclose($open);

?>
