Just copy and paste the code inside the textbox under the picture you would like on your website or webpage and paste it into your HTML! It's as simple as that!
If you would like to donate any animated buttons to me, just give me the picture through e-mail (either put it IN the mail or put it on the web and give me the URL. I will NOT accept attachments, as they might ruin my computer, even if it's already in bad shape).
