Make your own HTML signature in Gmail
Gmail is not allowing you to make nice HTML signature by default, ones like you can make in your Thunderbird, Outlook or any other mail application. However, every problem has it’s solution. One way or the other. Let me mention, this tutorial works only for Firefox or Firefox-based browsers, like Flock.
So, let’s start…
Make your own HTML signature like it is a web page. I like using text editor, but if you are not familiar with HTML, you may use any web page builder software. Only advice I can give you here is to make it small and clean. You may include image(s) also, but be aware that, if recipient is using Gmail, image will not be displayed by default, but Gmail will display a button “display images”. Also, on images, you need to fill “ALT” parameter so it can display text when image is not loaded automaticly.
Here is small example:
<html>
<body>
<table width="300">
<tr>
<td valign="middle" width="100" bgcolor="#EEEEEE">
<img src="http://www.flock.com/homepage/img/promos/referral.png" alt="Gift image">
</td>
<td bgcolor="#9999EE">
<font size="2">This is my test signature</font>
</td>
</tr>
</table>
</body>
</html> |
…which looks like this:

When you are satisfied how your signature looks, now we need to make use of it.
First, we must install plug-in called “Black Canvas Gmail signatures“. When you install and restart your browser, open Gmail and compose new message. Now you will see “Create Signature” or “Edit signature” button, once created.
In upper box, paste your HTML code. In lower box, you will see a preview.
Here is a preview for my real signature.

That’s all folks!
