It would be very useful to be able to order the images by timestamp, when marking mtps/gcps/cps. Most data is collected along a pathway, even if erratic, and having the ability to order images sequentially when marking would improve the user’s mental ability to ‘follow’ the images and ‘find’ tie points, especially where there are uncalibrated cameras.

Hi @cloughnan
As images usually have a sequential name (which follows the time it was acquired at), the existing feature of ordering the images by name may be what you’re looking for?
There are three little dots at the top of the image viewer and there is a “sort” option that works once you have a tie point selected, to help you with marking. You can also order by image reprojection, or by distance (which is the default).
