As most of you know by now, we've introduced a new system for displaying profile images. For most people the changeover will have been very smooth, but people using Internet Explorer 6 may well have issues, with people's names and pictures not displaying as they should.
We're working on this, and it will be resolved sooner rather than later. In the meantime, if you do have a choice of browser (we recommend Firefox) or can upgrade to a later version of Internet Explorer, we suggest that you do. IE6 is famously buggy, and not very good at displaying webpages in the way they should be.
