Key takeaway

Most missing image issues come from hosting, client image blocking, incorrect paste methods, or stripped HTML.

Visual example

Diagnose image problems before changing the signature

Separate hosting issues, recipient-side blocking, and paste-method problems so support does not waste time editing working HTML.

01

Check hosting

Confirm the image URL opens without login.

02

Separate remote image blocking from broken HTML.

03

Paste correctly

Install through the right email client settings.

Start with the fastest test

Send a test email to two different inboxes, ideally Gmail and Outlook. Open the email on desktop first, then on mobile.

Right-click a missing image placeholder and try to open the image address. If the URL does not load in a browser, the issue is probably image hosting.

Common reason 1: the image is not publicly hosted

Email signature images must be available through a public URL. A file on your desktop, a private cloud drive link, or an image behind a login will not reliably appear for recipients.

Use email-safe web formats such as PNG or JPG. Avoid SVG for email signatures because major clients do not render it consistently.

  • The image URL starts with https://.
  • The image opens in a private browser window.
  • The image does not require login.
  • The server allows the image to be requested by email clients.

Common reason 2: the email client blocks remote images

Some recipients block remote images by default. In that case, the signature may be correct, but the recipient needs to allow images for the sender.

You cannot fully control recipient-side image blocking. You can reduce risk by keeping alt text useful and making sure the text parts of the signature still work without images.

Common reason 3: the signature was pasted incorrectly

If a signature is pasted into the wrong field or through a plain-text editor, the HTML may be stripped. The result can be missing images, broken links, or visible code.

Gmail web users should add the signature in Gmail settings. Android Gmail users should set the formatted signature through Gmail Web, not only in the Android app.

Common reason 4: image dimensions are missing

Email clients are more reliable when images have explicit width and height. If image dimensions are missing, a client may resize the image unexpectedly or create layout shifts.

Mysignature output is designed around these email-safe patterns.

Before asking for support

  1. 1Confirm which email client is affected.
  2. 2Check whether the image URL opens in a private browser window.
  3. 3Test whether the issue happens for the sender, recipient, or both.
  4. 4Capture the signature editor and received email screenshots.
  5. 5Confirm whether the signature was edited manually after copying.

Create a signature with hosted images

Mysignature helps reduce missing-image issues by using email-safe HTML patterns, hosted assets, and setup guides for common email clients.
