Puzzle/problem viewing thumbnails

[Grant Bowker]

I like the concept of having thumbnails of images. They load quickly but let you see what images are available to look at. It took me a while to come around to liking them when the forum went from full size images to thumbnails a year or so ago, but I have decided I like the change. My puzzle/problem is that in the last day or two the thumbnail images whether viewed at home or at work seem to have become blocky or pixelated to the point that I can't really make out what they represent. The result seems the same whether using Internet Explorer or Netscape. Is anyone else seeing the same thing?
