How to add a Gmail signature

Problem
If you see a broken image in your signature, this is due to a bug in Gmail for non-Chrome browsers. To solve this issue, you need to upload your image on a service other than Google Drive (the one offered by default in Gmail) and add it via the URL in Gmail settings. 

Solution

  1. Go to Gmail’s General Settings
  1. Find Signature in the General tab and add your text signature
  1. Tap on the button to add an image
  1. Upload your image to a service providing you a direct link to the image (important: don’t use Gmail’s own uploader) and paste the link in the popup
  1. Select the right size for the image
  1. Enjoy your shiny new signature that will work across browsers and not just in Chrome 🎉
