Pics not appearing

Heeelp!

My pictures are suddenly not appearing – not in post body, not in the featured images.

See this post – you can see the ‘broken image’ thing is there:

I’ve uploaded via the media library, and also via the in-post uploader …nothing. I’ve tried different sizes too, and I’ve tried with JPGs and PNGs.

The media file is there – when I go to the library it’s there – but when I go to ‘view attachent page’ it’s just the little broken image icon.

Any suggestions? I installed one new plugin today (custom post order) – have deactivated that but no joy.

Thanks so much!
