Those secondary crater images are remarkable, and they look different from what I've seen on the moon, IIRC. The craters have been almost engulfed by a ground-hugging flow that is presumably from the same impact that created the craters, but must have reached the area after the craters formed (i.e. tens of seconds later).

You're right, there is no doubt that formed at the same time.

Beautiful view of Mercury.

I downloaded from PDS the latest batch of images covering the period 078.2014-260.2014. In this batch are a lot of photos taken from a height of less than 30 kilometers. Pictures taken from this altitude are significantly smeared, so on the photographs potentially taken from a height of 5 km should not expect any clear details.
For example, below are presented two images from a height of 29.83 and 29.66 kilometers.
