What specific issue is being faced with reading images from a database and applying a background image?

The specific issue being faced is that the background image is not being displayed when reading images from a database. To solve this, you need to retrieve the image data from the database and then encode it in base64 format before applying it as a background image in your HTML or CSS code.

<?php
// Retrieve image data from the database
$imageData = $row['image_data']; // Assuming $row is the result from your database query

// Encode the image data in base64 format
$base64Image = base64_encode($imageData);

// Apply the background image using inline CSS
echo '<div style="background-image: url(data:image/jpeg;base64,' . $base64Image . ');"></div>';
?>
