php rollover link and show image form databse that has same id

Question

I have a list of categories in a database that our echoed onto the page like so:

echo '<li><a href=#?id='.$row['category_id'] .' "> ' . $row['category_name'] . '</a></li>'; 

How would I echo that corresponding image(category_image) that is in the database when I hover over these links individually?

Do I hide a div and then have it appear on hover with the image inside? but then how do I transfer the id?

category_image is a path, not the actual image.

Answer 1

Just output the image as well, hide it via CSS and show it on hover. No need to make a roundtrip to the server to fetch anything. ;-)
