Your Gmail signature is your email's business card; is it not better with a logo or image?

How to Add a Gmail Signature Image

A logo, image or photo in your email signature helps promote you or your business. Find out here how to do your Gmail signature image right (even inline).

First, Why Fi?

Interbrand invented “Wi-Fi”.

They did not invent the technology (that goes back to a Viennese heroine, the graceful and smart Hedy Lamarr); the branding agency responsible for “Prozac” and “Bing” made up the word. “Wi-Fi” sounded just right and sophisticated with a due resonance of “Hi-Fi”.

So, “Wi-Fi” does not mean anything.

Wi-Fi or cable, we want to send our meaningful emails on their way through the net, we want those emails to end well, and to have them end particularly well, we have our hearts set on a graceful and smart image in the Gmail signature.

Let’s get started!

How to Add an Image or Logo to Your Gmail Signature

To insert an image, logo or graphic into your Gmail email signature:

  1. Make sure the image has the perfect size.
    What is the perfect size? Usually, just a little bit smaller. Shoot for some 300 x 100 pixels. See below for quick ways to shrink images.
    Make sure the image is also small in size on disk: avoid gradients and complicated images, and use GIF or PNG if possible.
  2. Ideally, make sure the image is available on the web. Gmail can do this for you automatically, but you can also add the image to Google Photos, for example. See below.
    • Note: The image has to be downloaded when the recipient opens the message. Depending on the settings (and possibly connection issues), that may not happen. Your signature will then display without the image.
      It is not possible to include the image as an attachment with each message.
  3. Click the Settings gear icon (⚙️) in Gmail.
  4. Select Settings from the menu that has appeared.
  5. Make sure you are on the General tab.
  6. With multiple addresses set up for sending, make sure the signature you want to grace with an image is selected under Signature.
  7. Put the text cursor where you want to insert the image.
  8. Click Insert Image in the signature’s formatting toolbar (it sports an image).
  9. To use an image right from your computer (and add an image to your Gmail signature without a URL):
    1. Go to the Upload tab.
    2. Drag and drop the file onto the Drag a file here area.
  10. To use an image already available on the web:
    1. Select Web Address (URL).
    2. Copy the address for the image you want to include.
      This can be as easy as right-clicking the image and selecting Copy image address or a bit more involved.
    3. Paste the address under Paste an image URL here:.
    4. Click Select with the image appearing.
  11. To change the image’s size, click the image and select SmallMedium or Large.
    • You can always go back to the original size by clicking Original size in the same menu.
    • Note: This only changes how big the image displays. The size of the image itself as it is downloaded in the email program or browser does not change if you insert an image using its web address.
  12. Click Save Changes to save the signature including its image.You have, I guess, noticed that the image stretches the line on which it appears to its hight and all you can do is move it left, right or center. See below for addressing this issue and, for instance, have the image appear to the left of your signature’s text.

Can I Have the Image Next to My Text in the Signature?

Yes; all it takes is a little tweaking.

To edit the placement of your Gmail signature image:

  1. Add the desired image to your signature. (See above.)
  2. Highlight and copy the entire signature.
    • Tip: Under Windows, press Ctrl-A followed by Ctrl-C in the signature editor, under macOS, press Command-A followed by Command-C.
  3. Open the HTMLG editor in your browser.You can use a different HTML editor, of course. I’ll use HTMLG as an example here.
  4. Paste your signature into the WYSIWYG portion of the editor.
    (WYSIWYG stands for “what you see is what you get”, and it portion sports a formatting toolbar.)

    • Note: If example text is present in the editor, make sure you highlight all of it before pasting.
  5. In the source code portion of the editor, look for the <img> tag that represents your signature image. You should recognize the URL in the src=”” attribute.
  6. To that <img> tag, add style="float: left;" to have your image aligned left with text floating around it, for example. For a right-aligned image, usestyle="float: right;". (See below for example code.)
  7. Make sure the image and signature display as desired in the WYSIWYG portion of the editor.
  8. Highlight and copy the full signature.
  9. Paste it back into the Gmail signature editor.

Signature Alignment Example

Let’s say the original signature looks like this in Gmail:

Heinz Tschabitscher
http://ladedu.com
The code for this signature is:
<div dir="ltr"><img src="http://ladedu.com/wp-content/uploads/2017/07/Heinz-Tschabitscher-Logo-216x105.jpg" alt="" />Heinz Tschabitscher</div>
<div>http://ladedu.com</div>
Now, let’s add style=”float: left” to the image to get the code
<div dir="ltr"><img src="http://ladedu.com/wp-content/uploads/2017/07/Heinz-Tschabitscher-Logo-216x105.jpg" alt="" style="float: left" />Heinz Tschabitscher</div>
<div>http://ladedu.com</div>
, which makes the signature look like:
Heinz Tschabitscher
http://ladedu.com
. We paste this right back into Gmail.

Can I Turn the Gmail Signature Image into a Link?

Yes, you can add a link to an image in your Gmail email signature. This lets you link the logo to your website, for example, or your photo to a bio page.

To link your Gmail signature image:

  1. Highlight the image with the mouse or keyboard.
    Note: Make sure the image appears highlighted like text would; the image context controls will also show, but it is not enough to merely click the image so it is selected and the controls appear.

    Highlight the image with the mouse or keyboard
    Make sure the image you want to link is highlighted (in blue here)
  2. Click the Link button.
    You will not get a linking dialog, but the image will be linked, and you can edit that link.
  3. Click Change under Link in the image’s context menu.
    Tip: If you do not see the menu, click the image again.

    Click Change under Link in the image's context menu
    Click “Change” for “Link” (note the default link to “/”)
  4. Delete the pre-entered “/” in the linking dialog under To what URL should this link go? on the Web address sheet.
  5. Enter the URL for the link under To what URL should this link go?.
    Tip: If you want a click on the image to open the reader’s email program or service instead with a new message addressed to you, click Email address and enter your email address (or, of course, Gmail alias address) under To what email address should this link?.
  6. Click OK.
  7. Click Save Changes.

What to Do If Your Gmail Signature Image Is Not Showing

Has somebody told you the supposed logo in your signature shows as a blank space? Are you unsure the image in your signature is working?

Let’s check things are working and tackle a few common problems:

  1. Open the Gmail signature editor (see above) and check the image is showing fine there.If you do not see the image or it appears broken, highlight and delete the existing image and re-add it using the steps above.
  2. Send yourself a test email using the signature.
    • You can do this with an email to your Gmail address, of course; to test for more issues, it is better to use a different email service, though—Outlook Mail, for instance, Yahoo! Mail or Zoho Mail.If you do note a problem with your Gmail signature image,
      • check the image’s size—is it too big?—and
      • examine the message’s source for anything odd if you are familiar with HTML code. You can do this in Gmail, for example.
    • If the image displays fine for you, chances are the recipient’s email program or service is blocking remote images by default.
    • With Gmail, you can only insert images into your signature using remote images. To see them, recipients will have to allow these images to be downloaded either globally or for you specifically.

What Can I Do to Mitigate the Bad Effect of a Signature Image That Does Not Show?

You cannot guarantee that the image in your Gmail signature will display for recipients. It is best, therefore,

  • never to include important information only in an image.

For example, do not add your email address, website’s URL or contact information to the image in your signature. Include this information as text instead.

If the image in your signature is important for the layout, you can have email programs and services display a descriptive placeholder in the image’s stead:

  1. Open your signature (including the image) in an HTML editor such as HTMLG. (See above.)
  2. Add the width and height of your image to the <img> tag with the width and height attributes.
  3. Optionally, add a text alternative to the image using the alt attribute. This will display inside the placeholder if the image cannot be loaded.
    • Example: If the code to your image is <img src="http://ladedu.com/wp-content/uploads/2017/07/Heinz-Tschabitscher-Logo-216x105.jpg"> and the image’s size is 216 x 105 pixels, you could make the following changes to ensure a placeholder image and a description:
      <img src="http://ladedu.com/wp-content/uploads/2017/07/Heinz-Tschabitscher-Logo-216x105.jpg" alt="[Logo]" width="216px" height="105px">

How to Add an Image to Google Photos for Use as a Gmail Signature Image

  1. Make sure the image is already resized. Google Photos will not let you shrink images.
  2. Open Google Photos.
  3. Click Upload.
  4. Select and double-click your signature image.
    • Tip: In most browsers, you can also drag and drop the image file onto the Google Photos page to upload.
  5. Open the picture you just added.
  6. Copy the image’s address for use in Gmail.
    • In most browsers, click on the image with the right mouse button and select Copy image address from the context menu that has opened.
