In PHP, what considerations should be made when choosing between storing image filenames in a database versus using PHP functions to dynamically determine the image file to display?

When deciding between storing image filenames in a database versus dynamically determining the image file to display using PHP functions, consider factors such as scalability, ease of maintenance, and performance. Storing image filenames in a database allows for easier management and retrieval of images, but can introduce additional database queries. On the other hand, dynamically determining the image file to display using PHP functions can be more efficient for smaller applications with fewer images. 

// Storing image filenames in a database
$imageId = 1;
$imageFilename = getImageFilenameFromDatabase($imageId);
echo '<img src="images/' . $imageFilename . '" alt="Image">';

// Dynamically determining the image file to display
$imageId = 1;
$imageFilename = 'image' . $imageId . '.jpg';
echo '<img src="images/' . $imageFilename . '" alt="Image">';
