Did I just make a big mistake?

After my normal prolonged hesitation, I decided to switch to the new Blogger Beta. OK. Then I wanted to add the 'Friend of Israel' image to the sidebar. It seemed the best way to do that was to switch to a new template, which would then open up the wonderful possibilities of using the drag and drop facility for customising. Did so. Now, not only can I not see how to add the link to that little image, but I notice that my own list of links has disappeared and will need to be re-entered one by one. Obviously, my hesitation to change was not long enough.
