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.

This simple little plugin gives each author on your blog the ability to setup a signature and to include it at the bottom of their posts.
The admin screen gives each author the ability to format their signature (a text area with HTML formatting enabled) and to indicate whether or not they want the signature on or off by default.
Regardless of the default setting, your authors may toggle the inclusion of the signature to ‘on’ or ‘off’ for each individual post at the bottom of the Write Post and Edit Post screens.
