Site Inspection - CameraScreen Explanation

[ShanP]

Hi, just wondering if anyone could explain the CameraScreen Screen in the sample app "Site Inspection."

Specifically, I am having a hard time understanding the "Done" button (submitting the photos).

Thanks.

After some testing, the onselect of the done buttuon is like this:

If(NewRecord,Navigate(NewInspectionScreen,ScreenTransition.Fade),
If(CountRows(CameraPhotos)>=1,UpdateContext({AddPhoto:Patch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,1)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,1)).Note)})}));
If(CountRows(CameraPhotos)>=2,UpdateContext({AddPhoto:Patch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,2)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,2)).Note)})}));
If(CountRows(CameraPhotos)>=3,UpdateContext({AddPhoto:Patch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,3)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,3)).Note)})}));
If(CountRows(CameraPhotos)>=4,UpdateContext({AddPhoto:Patch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,4)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,4)).Note)})}));
If(CountRows(CameraPhotos)>=5,UpdateContext({AddPhoto:Patch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,5)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,5)).Note)})}));
If(CountRows(CameraPhotos)>=6,UpdateContext({AddPhoto:Patch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,6)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,6)).Note)})}));
If(CountRows(CameraPhotos)>=7,UpdateContext({AddPhoto:Patch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,7)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,7)).Note)})}));
Navigate(EditInspectionScreen,ScreenTransition.Fade);Clear(CameraPhotos))

As I took pictures in camera control, it will save all the images to the editform

UpdateContext({AddPhotoatch(SitePhotos,Defaults(SitePhotos),{PhotoId:Max(SitePhotos,PhotoId)+1,Photo:Last(FirstN(CameraPhotos,1)).Photo,ID:Gallery3.Selected.ID,Note:Text(Last(FirstN(CameraPhotos,1)).Note)})}));

Can you please explain/clarify this part? Thanks.
