What are common mistakes users make when trying to insert images in a PHP forum?

Common mistakes users make when trying to insert images in a PHP forum include not properly specifying the file path or not checking if the file is actually an image before attempting to display it. To solve this issue, users should ensure that the file path is correct and that the file is indeed an image file (e.g., using the `getimagesize()` function). 

// Check if the file is an image before displaying it
$image_path = 'path/to/image.jpg';

if (getimagesize($image_path)) {
    echo '<img src="' . $image_path . '" alt="Image">';
} else {
    echo 'Invalid image file';
}
