Two Twitter Wordpress Plugins from Smahing Magazine

1. Twittar Wordpress Plugin: This plugin will show your Twitter avatars [avatar for comments] in comments in WordPress blogs.


Features:

• Loads user’s avatar by matching the email address to the user’s Twitter email address.
• If user doesn’t have a Twitter account, it first tries to load user’s gravatar. If user doesn’t have a gravatar, it loads a default image. This is an optional setting.
• You can set a 2-pixel border to the images (you choose the color).
• You can choose the size: we suggest 24, 48 or 72 pixels.
• You can set an image other than the default one to load if a user doesn’t have a Twitter account or a gravatar.
• It builds a valid image for you (with alt and title attributes, etc.) based on user details.
• Allows you to add a class to the image, so you can style it later.
