What type of picture file are you trying to insert. Most of the viewers
support a variety of texture formats (RGB, GIF, JPEG, BMP, PNG)
along with SFImage (data right in the WRL file). This is specified like:

Separator {
Texture2 { tree.gif }
Cube {} # or whatever your object is
}

Once u get comfortable with this you can change the way it maps using
Texture coordinates.

Adding ViewPoints may help. If no viewpoints are specified then most
browsers figure out where everything is and tries to fit that into the
window. By adding viewpoints you tell the viewer where you want to be looking
so you can put the camara (initial view) right in front of your space
station.
