HTML isn't really used for this anymore, it's done via CSS (Cascading Style Sheets). On the web currently, HTML pretty much just describes what to be displayed, CSS describes how it's to be displayed and JavaScript is used to provide function to a web page.
In HTML, you could use: align="center" as an attribute of the img tag to center it. Now it's preferable to use text-align: center CSS for the object containing the image (a div or p).
Positioning things on top of each other brings in z-axis and position CSS. Check out the CSS tutorial at http://www.w3schools.com . It's free.

This scenario would benefit from being set up as a recurring appointment, since it requires the same thing to be done every month on the same day. Susan is likely to forget this appointment every month, so a reminder like this would be useful for her. For the other cases, a recurring appointment would not be of much benefit since they do not follow a particular pattern time-wise.
