1. Go to the layout page, which allows you to add gadgets.
2. It will then take you to the add gadget, and layout page
3. When you get on that page, click add gadget.
4. The add image. I have seen loads of people try adding at html but the best way I found is to add an image. It may say Picture on yours, it does vary from blog to blog.
5.When you click on it, it should say Configure Image.
6. Put whatever title you want, I put 'Some of my lovely Bloggers'.
7. Choose the image of your friends/advertisers blog button and upload it by choosing the file button.
8.Then enter the link to their blog. Be careful that if you are copying it directly from the web address to delete one of the two https as I made this mistake!
9. And always make sure to save!!
Hope this helps and have fun adding blogs my lovelies!
