No images being shown in gallery

If you are getting a "Sorry, no images have been added to this gallery yet" error, the likely error is your gallery Image Order settings. Go to Sunshine > Settings > Galleries > Image Order. If you have selected "Order images shot (Images MUST have EXIF field "DateTimeDigitized")", then any images which do not have this EXIF data will not be displayed. Either change this setting or re-upload the images with the necessary EXIF data.
