The Single Photo field captures one photo. This photo could show the repair you made or give more detail about what needs fixing.
In the field settings, the "Allow Camera" setting is turned on by default allowing the user to capture a photo in the app. You can also enable the "Allow Photo Library" setting to enable the user to upload an image from their device. Additionally, you can select the photo's quality in the field settings, JpgNormal being the lowest quality and PNG being the highest quality. When adjusting the quality settings, please keep in mind that the photo's quality will affect the user's total submission time, as larger files may take longer to upload.
