To help with the question as to what is shown in the "foot picture" and the "dragging picture" respectively and how I think the camera changed position in between, I decided to go a little creative with the picture of the floorplan.
For reference, by foot picture I mean this one with JA's foot in it:

And the second dragging picture is the one where people upthread were wondering what is shown in there, whether the white line is the baseboard or the threshold between the carpet and the tile and so on:

I took the picture of the floorplan to show how I think the camera was positioned in each of those pictures. Mind you, I make no guarantees on scale, or where exactly along the hallway this is taking place. This is just a rough illustration on where I think the camera, JA and TA were in relation to each other. The yellow-ish area is everything that would be in the frame of the picture, everything that is not yellow would be out of the frame.
Basically, I think the camera got spun around in between the pictures, maybe from Jodi hitting it with her foot as she was dragging Travis along the hall.
In the first picture, the foot picture, the camera is pointing down the hallway towards the bedroom.
Then it got spun around almost ninety degrees and the next picture is actually taken with the camera almost facing the wall. It was taken at a point when Jodi had already moved past the camera, so she would be to the right of the frame and was in the process of dragging Travis through the frame, so to speak. The horizontal white stripe is the baseboard (is that what you call the line where wall and floor meet?), and the blood-covered object to the left would be Travis' shoulder or part of his upper body.
Again, I make no guarantees on angles or the accuracy of the positioning. I actually think now that in the second picture, the camera was not angled directly at the wall like I illustrated above, but still a little towards the bedroom area, but I hope this is able to convey roughly what I think happened in between the two pictures.
