I have a slight problem ...

I'm on the office (Home) computer as it's the only one that's connected to a printer. However, it's recently started displaying images in a REALLY poor quality. It seems to be only images that are on the internet, though.
I did think it was just Photobucket up until this afternoon, as Flickr and facebook images all seem to be OK.
However, I've just clicked onto MY website and they're showing up as really bad quality, too. Those images are hosted on the same server that they have always been and there have been no changes to that OR my website.
My laptop seems to display images absolutely fine, though. And that's on the same internet connection.
I've tried looking through the Mozilla Firefox options, but have found nothing about reducing image resolution to improve loading time and I've found nothing on the 'Control Panel' of the computer itself that hints towards why the computer would start doing this!
If anyone's got any ideas, could you help me out?

Thank you!
