Automatically creates an image banner with the heading of the latest post, for use on web sites or as a signature in discussion forums.
The banner image is contstructed from a template image of any size, on top of which text with a user-selected typeface, color and placement is placed at each time a new post is published (or the latest post is updated).
With the use of the image banner as a forum signature you can provide a way of always advertising your latest post on the discussion forums you frequent. The plugin automatically provides bbCode and HTML appropriate for use as signature code for most discussion boards.
