Presently, the SE offers "batch photo upload" without any control of photo order during upload or post edit.
If three photos are uploaded in the following order: Photo A is 400k, Photo B is 500k and Photo C is 300K, the SE platform re-arranges the photos in display as Photo C, A, B and allows no opportunity to correct the displayed order back to the intended order.
I request the ability to at minimum, re-arrange the photos to the desired order before the post is "shared". I also request that the SE software follow the order that the photos were uploaded regardless of size.
