Screen captures are important when blogging and having an easy way to capture images from the screen and embedding them into a blog entry is a key feature. SnagIt from Techsmith Corporation is a popular and very usable utility for taking such snapshots of screens.
When using Windows Live Writer blogging client software there are different plug-ins which integrates SnagIt with Live Writer. I first installed various versions from the “official” Plug-in website, but they all did not work for me and the version of SnagIt I have installed on my machine (SnagIt 8.0.1). After some Google searches I have found this plug-in which works for me!
