What to do when the customer skips the edit

Hello everyone,

I am using the FPD to make my customers upload a picture in the picture frame shown on the attached screenshot.

Unfortunately around half of my customers is not uploading a picture and then I am stuck with the text "Foto hinzufügen" on my exported print PDF.

Has anyone an idea how I could fall back on a photo without the frame when my user is not uploading an image?

I saw I could make the edit mandatory but then I will not sell products to customers who do not want the personalization.

Thanks in advance

Till
