There is no metadata on the raw NASA released images?
No, at least not on the photos published here.

The "Pacman" crater:





All the credits goes to ZLD from http://www.unmannedspaceflight.com/index.php?showtopic=8037&st=105 forum regarding the very interisting images you see below:

The "Pit/wall":

QuoteHere's a morph between SO13 and SO14 of the strange cliff sided crater.









And:

More craters with the "light colourish material":



QuoteHere's another morph. SO5 -> SO14, large sputtered crater.

the more I see these pictures of Ceres spots the more it seems like there's structures there, ive dropped the contrast right down on some of the pictures, like there's connecting parts to the brightest areas .. haven't they super zoomed in yet ? I would have thought they would have taken some pictures at higher speeds/ or lower ISO's to see if any fine detail can be made out in them.

or are they enjoying the tantalizing lengthy aversion :D

The top looks so interesting, they say it is flat. Why does the bottom of the mountain look so odd like see through or missing?

QuoteThe mountain, located in the southern hemisphere, stands 4 miles (6 kilometers) high. Its perimeter is sharply defined, with almost no accumulated debris at the base of the brightly streaked slope. The image was taken on August 19,

This changed many ideas I had read on the bright spots.

What you do mean by that? ???

Near the center at the very bottom, the outline of the mountain seems to contain craters and such not like the other sides? Is this an illusion from the angle? Is the angle perhaps just much steeper on that side?

I understand it now, thanks. :)

I think it's because we don't see the area in 3D, as probably that part is higher than the rest and the side of the mountain much lower than the rest in relation to the surrounding area.

New released Nasa Pic.  Ceres' Occator crater, with a resolution of 450 feet (140 meters) per pixel.

I can't see the image, so, in case more people can't, here's a link to a NASA page about that image. :)

The center white certainly looks like either an impact debris explosion, or even a volcano-like explosion, but the spots to the upper left are interesting.

We should get the updated pictures of Ceres soon I am so looking forward to it!

So is the spacecraft still there or have they been holding out on these closeups?

Looks a lot like rectangular structures with disturbed soil like a MINE :P

The verdict is in — mostly. The bright spots on the dwarf planet Ceres are probably made of salt, NASA's Dawn spacecraft has found.

Mysterious bright spots on Ceres are probably salt
Ice also transforms to water vapour in the dwarf planet's craters, creating an enigmatic haze

Sorry but I don't believe them.

Dawn is currently spiralling down to its final mapping orbit, which it will reach on or before 18 December. From there it will study Ceres from a distance of about 385 kilometres until the mission runs out of money to operate the spacecraft or it can no longer point itself in the right direction.
