With the Thickbox Announcement you easily can set-up an announcement, which will be displayed in a thickbox (lightbox). 
Several options let you control the apperenace and the frequency of the announcement. You can display any external 
content using an iframe or an inline content which can be edited using the standard wordpress editor.
<h4>Update Information</h4>
I’ve renamed my plugin since the plugin named looked very irritating. Since Version 1.0.3 the plugin is simply called Thickbox Announcement. 
If you are still using Version 1.0.2 no updates are displayed in the plugin overview of your wp installation. To perform an update 
you have to use the function Add New and search for this plugin. Click on Update to perform the automatic update.

This plugin allows to use the thickbox features for images and wordpress galleries without touching the html. It includes an option “Open in the same window” on the edit panel before inserting the image on your post.
For the native wordpress galleries the plugin inserts the “thickbox” class name and rel properties automatically.
You can also edit the html if you want to use Thickbox in any other links.
