Hello Bob,
To answer your questions:
1.) Open up the search module in your "site modules" area and you can change the module position assignment.
2.) Each of this is actually a module published to one of the s5 tab show module positions. As above, look in your "site modules" area for each of these modules.
3.) Make sure you are using a full URL, this means including
http://www.yoursite.com. If you did this then try pasting the URL in your browser address bar. If it doesn't show up then you know that you aren't correctly pointing to the directory where the image is located.
Regards,
