Images blocked in Outlook emails

Ever since I got Norton 360, every image in every email I receive or have ever received is blocked with the red x.  I used to have the option of right-clicking ‘show images’, but that’s not coming up anymore.  I also don’t have the ‘add to safe senders’ option anymore, that used to allow images to be shown from those approved addresses – not that that really matters, as even images from my identified safe senders are being blocked. 

 

This is insanely infuriating/frustrating & I need to know how to turn this off so my images show up again.  I'd also really like to know why Norton is messing with my Outlook & taking options away from me.  My OS is Windows XP & I’m using Outlook 2003.  & yes, before anyone suggests it, I already have the box for blocking images unchecked – it was never checked to begin with.
