The quality isn't the best ever, but I think we will be able to see what it is anyway. :)
The building to the right must be a spire. The top left picture is probably a Hatchery. Maybe the bottom left one is a morphing Sunken colony. Also, we can see larvas all over the creep.
*EDIT*
DeacoM messaged me and told me that the "Hatchery" actually is a "Zerg Nydus Pit", where you could upgrade Zerglings.
In this picture there are also a few units. Two Zerglings, a Hydralisk and a Defiler. I guess that the white thing is a marine.
The buildings look kind of weird. Luckily, the game went through some pretty big changes before the release. ^_^
*EDIT 2*
People have said it in the comments and I have got a few messages about it. Starcraft Legacy have a whole bunch of pictures both from the beta and alpha versions of Starcraft. If you click here you can see them all.
*EDIT 3*
Wihlner sent me four lovely film clips from the Starcraft beta version. The films are zipped into a package wich is almost 13 MB big. You can download it from Downloads » Utilities, or simply click this link.
As you probably know, all pictures are welcome. Please send the pictures you like to me by a PM, see link below, or by e-mail, [email protected].
