How can beginners in programming improve their understanding of PHP to troubleshoot issues like missing previews on a website?

Issue: Missing previews on a website can be caused by incorrect image paths in the PHP code. To troubleshoot this issue, beginners in programming can check the image paths in the code to ensure they are pointing to the correct location of the images on the server. PHP Code Snippet: 

```php
<img src="images/preview.jpg" alt="Preview Image">
```

In the above code snippet, make sure that the "images/preview.jpg" path is correct and the image file exists in the specified location on the server. If the image path is incorrect, update it to point to the correct location of the image file to resolve the missing previews issue on the website.
