Can't view pictures or graphics when sending or receiving in email

Outlook 2007. Was experimenting with attaching pcitures inside an email and
somehow now I can not view any pictures inside outgoing or coming in emails.
This includes the text or logo information inside business cards, and
anything else in a box that comes in your email. Example, emails like from
ticketmaster with upcoming concerts, all the pics are gone. However, when I
send the recipient can see my business card content, etc. One more thing...
also if I right click on where I insert the picture or where my business card
is at the very top middle, I can view the picture as long as I keep the mouse
right clicked down. How funky is that? I've gone through clearing filters,
allowing downloads in the trusted area. I'm at a loss. Can you offer up any
suggestions? The only thing I can think of is finding out how to restore
original outlook settings, and I can't locate how to do that either. Thank
you.
