How can PHP beginners improve their understanding of image manipulation and display functions when working with databases?

One way for PHP beginners to improve their understanding of image manipulation and display functions when working with databases is to practice using PHP's GD library for image processing. They can start by learning how to upload images to a server, resize or crop images, and display them on a webpage dynamically using PHP and MySQL. 

```php
// Example code snippet for uploading an image to a server and displaying it on a webpage

// Check if a file was uploaded
if(isset($_FILES['image'])){
    $file_name = $_FILES['image']['name'];
    $file_tmp = $_FILES['image']['tmp_name'];
    
    // Move the uploaded file to a desired directory
    move_uploaded_file($file_tmp, "uploads/" . $file_name);
    
    // Display the uploaded image on a webpage
    echo "<img src='uploads/" . $file_name . "' alt='Uploaded Image'>";
}
```
This code snippet demonstrates how to upload an image file to a server and display it on a webpage using PHP. It is a good starting point for beginners to practice image manipulation and display functions in PHP.
