In Surveyor, use ALT+U to get into 'fly' mode - you can then move around the model using mouse, direction arrows, and page up/down until you get the view you want to capture.
To get back to normal mode, use Esc.
Then open your screenshots in a photo editing program - and edit them as you wish. If you want to publish to the forum, make the picture 640 x 480. If you want it as a thumbnail, make it 240 x 180.
