First, Ovid Writes So Nobody Can Read

without knowing his little secret. It’s a good thing we know it!

Straight from The Art of Love, here in James Michie’s translation:

Safe and undetectable by the eye

Is writing in milk—later just apply

A sprinkling of coal-dust and presto! you can read.

Ovid, The Art of Love

So, there you have it: invisible ink some two thousand years ago.

Now, does the picture you have so laboriously added to your Gmail signature seem to be painted in milk? Let’s see if we cannot find some coal dust:

Gmail Signature Image Not Showing? Here’s What to Do:

Let’s check things are working and tackle a few common problems with an signature image in Gmail.

Check in Gmail’s Signature Editor

  1. Open the Gmail signature editor.
  2. Check the image is showing fine there.

If you do not see the image or it appears broken:

  1. Highlight the existing picture in the Gmail signature.
    • Tip: Position the text cursor right behind the picture, then press the leftwards arrow key () while holding the Shift key.
  2. Press Del or Backspace to delete the image.
  3. Add the picture to your Gmail signature anew.

Test Your Gmail Signature Image

  1. Create a new email in Gmail.
    • Tip: With Gmail keyboard shortcuts enabled, you can press c.
  2. Enter an email address you receive under To.
    • Note: You can use your Gmail address, of course. For more comprehensive testing of a Gmail signature image not showing it is better to use at least one alternative service, however—Outlook.com, Yahoo Mail or Zoho Mail, for instance.
    • Tip: Send the email to more than one of your addresses at the same time and check in multiple email services or programs.
  3. Click Send.
  4. Open the message and check for the signature image showing. Things to notice:
    • Does the image display at all?
    • Do you see a placeholder in its stead?
    • What is the image’s size? Does it show up way out of proportion?
    • Advanced: Is the message’s HTML source code correct? You can check this right in Gmail, for example.

If the picture displays fine for you, chances are the recipient’s email program or service is blocking remote images by default. If you hear from more than one person that your Gmail signature image is not showing (but it displays fine for others), see if those with display problems do have something in common—an email program or service, for instance.

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. Otherwise, a Gmail signature image will not show.

Gmail Signature Image Not Showing: FAQ

What can I do to mitigate the dad effect of a Gmail signature image not showing?

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.
  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="https://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="https://ladedu.com/wp-content/uploads/2017/07/Heinz-Tschabitscher-Logo-216x105.jpg" alt="[Logo]" width="216px" height="105px">
