I would not worry about it much. There was some variation in the laser markings and the actual knives around the time that BladeHQ started selling the stone washed version, knifeworks had their own specific run made which was stated to be the blasted finish.
Blasted finishes do not reflect light well at all, think of the way the Sebenza handles look. Blasted finishes will show wear much more readily than any of the others, because of the way the surface looks. It also increases the ability for th steel to rust because in essence the pores of the steel are open (think of the texture of a sheet of sandpaper).
Stone washed finishes look like the ZT 0562 posted above, they reflect light but it is made to look as if it is somewhat "beat up", in order to hide scratches and such. Think of the way particle board looks, it's kind of the same aesthetic.
Satin finish is when you have a nice and clean. somewhat polished finish where the grind pattern goes in only one direction. Think of about Spyderco knives, 99% of them are satin finished. It won't be a full polish, but it will be nice and clean with distinctive and uniform grind lines.
If you want to upload pictures to the forums, use a photo hosting site, just keep the size of the pictures reasonable. FLickr, imgur, photobucket are a few to name, and they all have tutorials/instructions on how to get pictures to show up on forums.
