Installation is simple. Just drop the updated MetaBlog.ashx file into the /blogs/ directory of your site, and you are done! All the code is inline. You can also set some AppSettings parameters in your web.config as far as maximum attachment size, allows extensions, and a few other settings. By default we only allow images, but other file types are supported – they are simply added as links.
This update adds support for the newMediaObject MetaBlog API which will allow you to use services like LiveWriter or BlogMailr to easily add images to your posts. In the case of BlogMailr you simply write an email and add the images inline (drag-and-drop them between text) or as attachments.
