Thanks for the replies, guys. Yes, my research also concluded that the problem is server-side. My purpose in posting was that I hoped Glenn reads these threads and could follow up. I finally installed an add-in to Firefox that allows me to save large photos, albeit with two extra steps.
Regarding the past update of the site... Certainly there are problems with accessing photos uploaded much earlier, but the threads I mentioned in my posting only go back nine months or so. Maybe Glenn with check with his hosting admin and find out if a possibly newly-install version of PHP requires some adjustment of the SOHC image path or maybe Database mapping. All I know is, it shore don't work like it usta!!!
And as long as I'm ranting... I still don't know why my "notifications" come into my email infrequently and sporatically. I hope the site isn't paying much for their hosting. Otherwise, somebody's taking it in the shorts for support! Oh, well. At least it doesn't time out like it did in the "bad old days." RR
