What are the potential pitfalls of replacing the HTML button with a custom image in PHP forms?

Potential pitfalls of replacing the HTML button with a custom image in PHP forms include accessibility issues for users with disabilities who rely on screen readers, as well as potential compatibility issues across different browsers and devices. To solve this issue, it is recommended to use CSS to style the HTML button instead of replacing it with a custom image.

<button style="background-image: url('custom-image.jpg'); width: 100px; height: 50px;">Submit</button>
