hello,

i tried this but it only shows the name of the image that should be there and not the image.

Code: Select all

    <?
    
    $path = "../news_pics/$post_image";
    echo "<img src=\"".(file_exists($path)) ? $path : "" . "\" />";
    
    ?>

Sorry, I've been typing this code on a mobile phone so I left out parenthesis..
The code should be:

Code: Select all

    <?
    
    $path = "../news_pics/$post_image";
    echo "<img src=\"".((file_exists($path)) ? $path : "") . "\" />";
    
    ?>  

KR,

Add style="width: 123px" attribute into the img tag

<?
