When there is an image question in an activity, participants have two ways to add a photo on the mobile application:
They can use the in-application option to take a photo.
They can choose to upload a previously captured image from their mobile device files.
Once an image is selected, the participant will be prompted to either retake or use the image. If the image is used, the status bar will indicate that the image is uploading. The green check mark indicates that the image has uploaded and been saved in draft form. The activity can then be submitted.
Once an image has fully uploaded to the collector, the participant can choose to submit the activity or even upload or take an additional photo.
