1) Is it possible to determine whether back or forward should exist? 

if back history exists then
display back button 

if forward history exists then
display forward button 

2) Is it possible to determine whether a page has a background image? 

if bacground-image exists then
perform some action

I haven't tested this, but could you say:
if(document.history.go(-1))
{
	execute some code;
}
else if(document.history.go(1))
{
	execute some other code;
}

???

I'm not sure about the second part, except to check for the presence of
*any* images using document.images.length.
