Text to Image Mouseover

Ok guys I’ve got a new page on my website and I have a list of titles that when people move their mouse over they can both click on to download a file but also have an image pop-up showing them what they are downloading.

ie

Aircraft 1
Aircraft 2
Aircraft 3

Moving over ‘Aircraft 1’ would either add an image or replace the text with an image that could then be clicked on to download the file it links too. Moving the mouse away from the image would remove the image and bring the text back by itself.

Thanks in advance for anyone who can help. ??
