What are the limitations of embedding links in images using PHP?

When embedding links in images using PHP, one limitation is that the link may not be accessible to users with screen readers or those who have disabled image loading in their browsers. To solve this issue, you can use the "alt" attribute in the image tag to provide a text alternative for the link.

<img src="image.jpg" alt="Description of the image" onclick="window.location='http://www.example.com';">
