Ok, first of all I suggest either www.homestead.com or www.geocities.com for easy web page building. It takes a little while to learn how to do everything. You can search around the internet for free background or free images and add them to your site. You right click on them and save them to your computer then you have to upload them to the site. There will be a lot of trial and error while making your first page. Just test things out and you can always delete anything if you don't like it. Homestead and Geocities both offer templates to make things even easier. I am pretty sure both sites also have sections where they explain more to people who don't know what everything does. (Yeah I just looked and Homestead has a Take a Tour and Tell Me More link).

I had the site with the spay/neuter buttons bookmarked but I can't seem to find it right now. Here is another site with a few buttons like that on it: http://www.geocities.com/Petsburgh/Z.../graphics.html
I will get back to you when I find that other one with more buttons.
