Of course, I'm dealing with images, not HTML content, so META tags are 
right out.

But I added this as a header (using the same mechanism as the previous 
example) with no luck.

I guess I'm drifting into the HTTP standard for requesting images, 
which is a bit outside the scope of this list.

Perhaps my logs will be helpful in discerning what my browser thinks 
its doing. If anyone has any other insight I'd sure appreciate it.
