There have been many Greasemonkey scripts and Firefox addons that do the job of adding pictures and links on Gmail signatures. As you know Gmail, on its own, doesn’t support the use of html and pictures in its email signatures in order to prevent misuses. So these scripts and addons have been the favorite lot of many who wanted to spice up their emails a bit. However since the new version of Gmail debuted, many of them have ceased to work.
But luckily here is one script called Gmail HTML Signatures that still works. It not only adds pictures and links on your signatures but also enable float. In other words, when you are replying to an email, your signature will be visible just below your message and not after the copy of the original email embedded in your reply. See screenshot of a signature below.
For newbies, please note that you first need to install the Greasemonkey addon on your Firefox browser and then this script. After you have installed the script, when you open your compose editor, you will see that just after the ‘From:’ section, you will see a link called ‘Create Signature’ . When you open that link, you will see a window where you need to add the html code of whatever signature you have created.
If you don’t know how to create a html and want a quick solution, you can use a free online WYSIWYG editor like this one at Real Graphics. Create your signature, format it well, add the font colors and the picture. When you are through, click the toggle (< >) button and copy the html code from there.
Remember if you using pictures, be sure to fill the description of the picture in the ‘Alternate Text’ in the upload window. Whatever you fill there will come out in the alt=”…” section of the html code. For example: alt=”StumbleUpon”.
This will ensure that the image description is shown whenever your email recipient can’t receive html emails. Just like in the screenshot above.
