Thanks Balinor, but this isn't exactly what I'm after.

What I would like is when the user views that category of products the original thumbnail (which i think is currently product_thumbnail.tpl) appears on screen.

When the user clicks on the product they would like to view a new screen appears with the detail of the product, with the option of choosing a quantity to add to cart.
In this screen currently the same thumbnail appears as in the category screen. What I would like to do is make a different image appear on the details screen. That is, where ever this section of the code for only the detailed screen points to the original thumbnail I'd like it to point it to the detaled image thumbnail.

Not sure if this all makes sense so:-

- When user clicks on category 1 - Product thumbnail 1 is displayed
- When Product thumbnail 1 is selected - details of the product appear with the Product thumbnail 2

Hope you can help.
