Script to show different image for different posts by their ID

    Hello!

    I am trying to create a short script that would show different image (within The Loop) for different posts by their ID. So should I create a post with ID 1 and create an image named “1.png”, it would be displayed normally.

    But should I forgot to prepare an image or should user view a post that was published long time ago, it would display some random image (I think I will use image rotator for that but let’s assume I will use “404.png”).

    <?php
if ( file_exists("<?php echo site_url(); ?>/images/post_images/<?php the_ID(); ?>.png") )
{
<img src="images/post_images/<?php the_ID(); ?>.png" alt="<?php the_title(); ?>" />
}
else
{
<img src="images/post_images/random/404.png" alt="<?php the_title(); ?>" />
}
?>

    When I try to use this code I get a blank page. I guess there is something wrong with my syntax – in particular, I am not sure how should I connect WordPress-specific PHP code with strings (I don’t know too much of PHP). Can anyone help me? ??

    I obviously want to include this code in index.php, not within the post content.

    Thanks in advance!

    Got some guidance on another forum:

    <?php
if(file_exists("images/post_images/".get_the_ID().".png"))
{
echo "<img src='images/post_images/".get_the_ID().".png' alt='".get_the_title()."' />";
}
else
{
echo "<img src='images/post_images/rotate/rotate.php' alt='".get_the_title()."' />";
}
?>

    Problem solved!
