Is anyone else out there experiencing image loss in blog.co.uk when viewed with Internet Explorer 7?

For some bizarre reason I can't quite put my finger on, I started having image problems with Blogland and IE7 yesterday.

Basically it's this: any images on a blog that I have previously visited appear as placeholders with the little red cross (broken image) and this includes avatars. Very weird...

Before I delve deeply, I just wondered if anyone else has/has had the same problem?
