Image Is Available In Site B Help

I have two Classifieds websites that I linked with each other the problem I'm having is getting to show images on Site A to show on site B and visaversa, That is a difficult, as site A couldn't do a file search in site B (security limitation). So, all I can do is not directly displaying image in site B by using <img src="examplesiteb.co.za/images/a.png">, instead refer to a script to check if the image is available in site B, eg: <img src="examplesiteb.co.za/image.php?a.php"> is there any body that could Help me with this

 

Do you know the variable used for the actual image?
Lets assume its called $img
You could try the following:

<?php
 
$host = $_SERVER['HTTP_HOST'];
 
$image_url = "http://$host/images/$img";
 
$image = $image_url;
if (empty($image)) {
    $image = "http://siteB.com/images/$img"; // Change the url for opposite site or point to a default image
}
 
//echo $image;
 
?>

Thanks for the quick response, this is the php code that calls in the image(s)

Line 159-175 is if the images does not exist to use defualt image
Line 183-218 are the once for listings and details pages. I will see if I can implement yours to this
