Regarding

http://support.google.com/webmasters/bin/answer.py?hl=en&answer=1229920

to scrolled down section ''Examples'' to the point ''1.'' to the second code line which is:

<a rel="me" href="https://plus.google.com/105240469625818678725/"> <img src="//www.google.com/images/icons/ui/gprofile_button-16.png"></a>

On the page says that I have to add this line to the Contact Me page of own website in order to get Google Profile button. Exact code which one should be copy and pasted I am able to get here:

http://www.google.com/webmasters/profilebutton/

Questions:

1). As you can see on the second URL, to make Google Profile button I need to use "author" tag and not "me" tag. But the first URL which I showed (the line in this message above) shows that I have to use "me" tag and even without this: width="32" height="32". I am already aware that I have to type (second URL) my own Google Profile URL. So do I just MANUALLY ( ! ) change this:

<a rel="author" href="https://profiles.google.com/109412257237874861202"> <img src="http://www.google.com/images/icons/ui/gprofile_button-32.png" width="32" height="32"></a>

to this (note: two changes done):

<a rel="me" href="https://profiles.google.com/109412257237874861202"> <img src="http://www.google.com/images/icons/ui/gprofile_button-32.png"></a>

Is this correct? I assume that plus.google.com is the same as profiles.google.com (both is URL of Google Profile).

2). If I was wrong with my first question then the second answer probably won't be even useful but still: Where exactly should I paste the code:

<a rel="me" href="https://profiles.google.com/109412257237874861202"> <img src="http://www.google.com/images/icons/ui/gprofile_button-32.png"></a>

inside Author Page of own website? I think it doesn't matter where. Also: will this icon be for sure enough or do I also have to make such anchor text with rel me in a ''shape'' of text (for word sentence such as ''Look At My Google Profile'')? Or is just icon really enough?

3). In the same section (''1.'') of the same page (link [first one] provided above) it says that I need to use first author tag to link to Author/Contact Me page of own website in order to later use Me tag. But I think in the explanation is little mistake. Shouldn't be instead of:

<a rel="author" href="http://www.cnet.com/profile/iamjaygreene/">Jay Greene</a>

this:

<a rel="author" href="http://www.cnet.com/profile/iamjaygreene.html">Jay Greene</a>
