What potential issues or errors can arise when using the image functions in PHP?

One potential issue when using image functions in PHP is memory exhaustion, especially when processing large images. This can lead to script execution errors or crashes. To solve this, you can increase the memory limit in PHP configuration or optimize the image processing code to use less memory. 

// Increase memory limit
ini_set('memory_limit', '256M');
```

Another issue could be errors related to missing or incorrect image file paths. To solve this, you should always check if the image file exists before processing it.

```php
// Check if image file exists
$imagePath = 'path/to/image.jpg';
if (file_exists($imagePath)) {
    // Image processing code here
} else {
    echo 'Image file not found';
}
