Hi Mari,
Thanks for reaching out to us!
So the way Fancy Cards work is:
1. You select which card you want to use from the left panel
2. You drag any images you want to customize from the Photo Basket (at the bottom of the editor) onto the photo area (a white square appears while dragging when a photo can be replaced)
3. You click the blue “Done: Customize” button (up the top right of the editor)
4. You can then click any text you want to customize and edit it on the left text panel that appears
Note that not all images and text are editable.
Let us know if you have any further questions or issues.
Thanks!
– Ben
