What potential pitfalls should be considered when using galleria.io for creating galleries in PHP?

One potential pitfall when using galleria.io for creating galleries in PHP is that the images may not load properly if the paths are not specified correctly. To ensure that the images are displayed correctly, it is important to use absolute paths when defining the image URLs in the gallery.

// Define absolute paths for images in the gallery
$image1 = "http://example.com/images/image1.jpg";
$image2 = "http://example.com/images/image2.jpg";

// Initialize Galleria with the absolute paths
echo "<div id='galleria'>";
echo "<img src='$image1'>";
echo "<img src='$image2'>";
echo "</div>";
