For your personal website to work, you need to include a picture of yourself first. You can also add a logo to the website, but it is not required.
1. Log into your Walkthrough Account at www.getawalkthrough.com
2. Once you've logged in, Click "Account Settings" in the upper right.
3. Then click "Choose File" underneath Personal Photo, and pick one from your computer.
4. Once you upload the picture, click "Save Your Info" and you're all set! The same process applies for adding a logo.
