In response to needing more information, FreshImage1, FreshImage2, and FreshImage3 refer to the types of images imported by the user. The user will have already selected these images from the prior view controller.
The app has no problem sending the correct image data to SMS, as when three photos are available, the text message attaches them correctly.
The issue is instructing the app that they can be sent even if fewer than three photos are present. Right now, if any less than three photos are available when "Submit Now" is pressed, then the app crashes.
Here is the complete code for reference:
