What are the potential issues with storing image URLs in a database, especially when it comes to software migration or path changes?

When storing image URLs in a database, the potential issue arises when software migration or path changes occur. If the image URLs are hardcoded in the database, it can lead to broken image links when the software is moved to a different server or when the image path is changed. To solve this issue, it is recommended to store only the relative path of the image in the database and dynamically generate the full image URL based on the current server settings.

// Store only the relative path of the image in the database
$image_path = "images/image.jpg";

// Dynamically generate the full image URL based on the current server settings
$base_url = "http://www.example.com/";
$image_url = $base_url . $image_path;

// Output the image URL
echo $image_url;
