Possible to set embedded websites display position or size?

Is it possible to set embedded websites display position? I’d like to make a smaller size and put it in the bottom of the site so I could still interact with people in Gather space.

I saw there are object properties but didn’t know where to find what’s the available variables.

The properties of an object are set based on the object type. Currently, I do not think there is a way to have an embedded website show up as anything other than full-screen. The smaller images you may have seen were probably for video embedded and image embedded objects. Website and pdf objects do not have a preview option.
