For some templates, and maybe just for a change, those rounded images can look very good. I'll show you CSS you can add to my hacks, and one Blogger gadget, to make images round. In my hacks you should add the CSS in the code before </style>.Better recent comments gadget
Add this style:
.recent-comment-ico img {
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
