The homepage of your instruction guide is a great place to introduce yourself to your students.
An avatar can be a fun and humorous way to introduce yourself to students. Voki and Blabberize are two great tools for creating animated avatars.
If avatars aren't your thing, try personalizing your guide with a quick video greeting. As long as you have an Internet-ready device with a webcam and microphone, the following two tools will allow you to capture a brief introductory video.
LibGuides provides built-in features for professionally personalizing your pages.
Chances are, there's a photograph you've captured that says a lot about who you are. Feel free to use personal photos of landscapes and scenes to inject a bit of your personality into your instruction guide. If you don't have any photos, try Pixabay. All images and videos are in the public domain.
