Unfortunately you cannot have photos from New Dropbox showing "in line" unless you pay for their Pro service (and why should you if you can use Photobucket or Flickr for free? ) If you are lucky enough to have the older version of Dropbox that has a "Public Folder" like I do, then it is really easy to right click on your photo and "copy public link" You can post a LINK to your photo from New Dropbox by clicking on the chain "get a link" icon and posting it directly into the text box (without using image tags). Hope that helps and clarifies things.
