By default, Tryst displays photos sorted in the order they were uploaded, with the last photo you uploaded shown first in the list. If you want to control the order photos appear in your gallery you can set your preference in the photo management view from your dashboard.
Set your photo order
Log in to your Tryst account and go to the Dashboard.
Select Manage Photos in the Photos section.
Under each photo is a number field, enter a number in each field to determine what order they are shown in, with lower numbers shown first and higher numbers shown last. If multiple photos has the same number, the last uploaded photo will be shown first.
NOTE: The change saves when you click out of the number area, there is no need to click a save button!
