OK. Thanks for that; if it turns out not to come to anything, I might consider switching to IMG200 - for visual effect if nothing else. Any image has greater impact than a link, I suppose, even if it is almost completely unrepresentative of what the actual picture looks like.
I did try IMG200, but that compresses the images to such a size that you can't actually see them (they're technical pen on paper, you see). If you think it'd be better if they were IMG200, then I'll change it, but I wasn't too keen on how it turned out.
