Disabling forms with javascript on submit to prevent double submit

General Questions About Image Maps
First off, I noticed that you can place the <map> tags anywhere in the document and the image map will work just fine. So, is it common practice for people to put the <map> tags in the <head>, or is it better practice to have it in the <body> immediately following the <img /> it corresponds to?
