Hi James, Thanks for contacting us!
The Photo Basket can be found at the very bottom of the editor when creating a collage or editing a photo. You can minimize it by clicking the words “Photo Basket” so that it becomes very small, and then clicking these words again maximizes it again. It may be that you accidentally minimized it, in which case you should still be able to find the words “Photo Basket” down the very bottom left of the screen.
Let us know if we can be of any further assistance!
