I see the pictures in post 7 just fine.
The problem is on your end.
C98’s Twitter-hosted photos show up fine for me. But it is best practice to not “direct-link” to photos on other sites (considered to be bandwidth theft). Host on a server you own or choose a photo sharing site like “Photobucket”, “Imageshack” or even “DropBox”.
