No - you should be able to display images in the post - just like anything else. What you do need to be conscious of is how many characters you're allowing.
For example, if you're allowing 200 characters, the HTML to display an image might get opened
<img src="http://wwwwwwwwwwblahblahlbh
But it can get "cut off" leaving an open tag on the page and that can really mess up the layout. If you're careful with the size limits, make sure it's allowing either "full" text or a long enough limit to allow all the HTML tags to get closed to preserve your layout.
But I display graphics in the news box all the time
