New Data Check Period Input
This input field controls the time (in minutes), to check
the server for new images to be displayed. This will
update the timestamps of images available in the "Start
Time" and "End Time" dropdowns. It will also affect the
images that are displayed when the "Automatically Update"
checkbox is checked.
Automatic Update Switch
The automatic update switch, when checked, will cause the
"Start Time" and "End Time" dropdowns to disappear and an
"Images to Display" input field to appear. This feature
will display the latest "N" images, where "N" is the
number entered in the "Images to Display" field. This
feature uses the "New data check period" input field to
determine how often to check the server for new images.
Every time there is a new image, the image sequence is
updated and the newest image is appended and the oldest
image is discarded. The change of input field values when
checking on this checkbox is depicted below.
