Nope, something has changed in the way the site handles avatar pictures. If the link is to a very large picture, the site may or may not resize the image as it use to. I've noticed a few other new features here and there (like the "strikethrough" option on the Post a Reply box). My assumption is the hosting site and utilities HSBBW is using have gone through an upgrade.
If anyone is looking for smaller college avatars, here is a good site to use:
College Baseball Logos . Just scroll down and click on the beginning letter for the school.
