UPDATE (02-25-2005): See comments below for an updated version.
Michael Bester has put together a plugin for WordPress and Textpattern that makes it really easy to use my FlashObject embed method in your blog.
Go check out his post about it to get the files and all the info you need to use it.
Geoff – I just wanted to give you a heads up about an update to the plugin. It has a number of bug fixes and is much easier to install. Get it here.
