I use Flickr just because I already have an account there, and I've never had any problems. I understand the precautions (well, the concept of them, the nitty-gritty details of bandwidth and such might still escape me), but I truly hope that such a change is temporary. Sticking with the example of the razor club pages, I really feel it detracts from the fun having to click on every picture. I've already heard matching concerns from someone on dialup, and I thought at first people with slow connections might be the ones to benefit from this/partly the reason for it. As much as I hate to make a suggestion that might lead to you keeping this change, perhaps use larger thumbnails?
