Help with Hotlink PLease

[edpudol]

I have 10 images in my site with the same file name but different size.

I allow other web master to link to this image.

e.g

<a href="http://www.mydomain.com"><img src="http://www.domain.com/image.jpg"></a>

What I want to happen is that I have the control which image to displayed on the site who link to my site. For example site a I want that it display the large image and site b display smaller one and so forth.

How could I do this? Thanks in advance

The way I see it, you have to acces your image with php rather then directly. So the picture should be something like

<img src="http://yourhost.com/image.php">

Inside image.php you should check what is the value of $SERVER['REMOTE_ADDR'] (for IP) and depending on it send appropriate headers for jpg and the content of a chosen file. Pseudocode would look like:

switch ($_SERVER['REMOTE_ADDR'])
{
  case "x.x.x.x":
  case "y.y.y.y":
           $filename="image1.jpg";
           break;
  case "z.z.z.z":
           $filename="image2.jpg";
           break;
  default:
           $filename="image0.jpg";
}
SendJPGHeader();
SendContet($filename);

Yes, that's the pseudocode I guess but the problem is how could I send back the image to the requesting site.

this is now the problem

SendJPGHeader();
SendContet($filename);

You basically said it yourself.

This is now the problem:
SendJPGHeader();
SendContent($filename);

There are functions to do exactly those things. [man]header[/man] and [man]readfile[/man].
