Thumbnail in the preview

Hello!

I am using the JQuery version of FPD for designing bottle labels and the preview currently shows two customized sides of the label.

What I need here is the ability to preview the final product(the whole bottle) on designing stage of the label. I know it could be solved by putting pictures of the whole bottle in the designer, but it's not really an option for me since I only need to email the two sides of the label and nothing else.

What could be the possible solution for this? Am I missing something?

Thank you!
