Good enough, Ed. In truth, it really didn't take that much time to do, so it's probably the way I'll handle things from now on - unless I get in a hurry or something. (Not that I've been that prolific a picture-poster of late.)
As for the large image loading fast - this example is just a bit under 200k in file size, which is in the range I like to keep to for all web images. For reasons having to do with how some of my tools work, even my BW images are kept technically RGB, so you should see no difference between BW and color from me. I'm suspicious that it's loading so fast for you now because you've still got this morning's download in your browser cache.
