[quote author="brahdaz" date="1335154914"]I'm a novice coder. I'm sure I'll be able to post a main article on the page, but what about the thumbnails? And how will the main article move to the thumbnail once I post a new main article in its place?[/quote]
you can get the news articles ordered by its posted date from the database and put it in to a html table.
before attempting to do thumbnails i recommend doing a simpler version and then implementing from that position.
CI has an image manipulation class which is very easy to use
