Popup Image As Default In Product Detail View

How can I make the large popup image the default image shown when viewing the product details?



I create my own thumbnails, and this is the default image for both product views and detailed view. I suppose if i change the sort odrer of the images in the detailed view would be 1 workaround.

or not showing the thumbnail at all on the detailed view would be the best option. Any Ideas?



Btway, I also create my own popup images.
