I'd like the possibility to specify displaying an image preview for YT videos, just like for the sitemap, but for the page as well. In other words, that would enable displaying the graphic of your choice as opposed to the first frame of the YT video, which sometimes can be just a black screen, which doesn't look great on the website

For example, see http://www.chezrossi.net/kronoscopie/neo-endorphin.html where some of the videos do not look great.

Also, it would be useful to add the possibility to select a video that has been placed in a DropBox public folder so it can be streamed like YT or Vimeo. Placing the video in the Internet File box doesn't work well.

As DropBox is a very reliable service that can host large files, it's useful to be able to stream a large video as opposed to several small ones on YouTube.

Thanks.
