These images should be in order of Date / Time taken in descending order... newest first. This of course may not always be so due to EXIF data not being accurate or stripped of that data.
A note about products that require multiple selections. These need to be added to the cart before you can select images for the product. For example when you add greeting cards you must select 25 images, if you want all the images to be the same, you must click to add that image 25 times. You can select from most of the images in the stock gallery (up to 25 different images) to use as greeting cards, once the process is started you must finish it, unless you remove the greeting card from the shopping cart.
