Thanks, glioma.
It is very annoying to have to wait so long.  I finally just blocked the images from hitsunlimited.com, and the response time is now excellent.
The problem just appeared out of nowhere, so they might have made a recent change with YaBB 1 Gold - SP 1.3.1, the board software product.  If you say "View Source" using a Microsoft browser it shows the code to accomplish the image download.
Of course, it is a matter of advertising money vs. our viewing pleasure.   Sometimes there is a strong conflict and both sides are determined to stand their ground.  Some would argue that the advertising link is necessary in order for the facilities to exist.  
I just want to enjoy the forum without long waiting periods for some obscure link at the bottom of the page.
Meanwhile, I don't mean to make the slightest tiny criticism against this wonderful forum.  It is, far and away, my most favorite place.
Unfortunately, I sold my R9S because of a little arthritis which made operating the slide difficult.  Still, Once a Rohrbaugh owner, always a  Rohrbaugh owner.   
 Thank you, rohrbaughforum.com for being here.  You are much appreciated.
