It is possible that you do not want to take a photo of someone because you already have his/her photo. If this photo is in one of the usual formats (bitmap, jpeg, png, etc.), you can use the Import photo function indicated in red to import it and display it on the card that you have opened in CardExchange® Producer. You can then save the photo in the database.
If you click Import photo, you enter a dialog window that allows you to select the photo file.
If you have found and selected the file, click Open and the photo will be displayed in the Image Editor window. Here you can crop the photo to the right size and perform any other editing operations.
