If you clicked "Add to Cart" and watched your images upload you might get worried when the inside image does not show up as it's uploading. Don't worry, it's OK the site saves both images but you only see the outside in the preview.
Unfortunately there is no way to see the image in the cart once the file is uploaded. However if you did save your design before you clicked "Add to Cart" then you can confirm the inside image by reloading the preview.
Additionally if for any reason the inside image is not attached to your order we will contact you before printing it but this is mostly due to customers not uploading an image at all to the inside panel.
