You don’t have to be an HTML expert to send rich, compelling email messages that command attention. Like Outlook, Mozilla’s Thunderbird email client gives you the ability to use HTML to add formatted text and graphic to email messages. You also have the option to create HTML signature files that Thunderbird can use to embed a custom signature you create. Custom signatures may consist of text, images from your hard drive or pictures that reside on the Web.

Step 1

Launch Thunderbird and create a new message.

Step 2

Click "Options," click "Format" and then click "Rich Text (HTML) Only." Click "Insert," and select "Image" to view the Image Properties window.

Step 3

Click "Choose File" to display your computer's files and folders. Double-click the image you would like to use as your signature, and then click "OK." Thunderbird displays it in the composition editor. Type optional text above or below the image if you'd like that to appear in the signature as well.

Step 4

Click "File" followed by "Save As," and then select "File." Type a name you'd like to call the file in the "File Name" text box, and click "Save."

Step 5

Click “Tools,” select “Account Settings” and click the account name you’d like to manage. Put a check mark in "Attach the Signature from a File," and click "Choose" to display a file selection window.

Step 6

Find the file you saved and double-click it. Click "OK" to save your changes. Thunderbird will begin inserting your image signature in all new messages you create.
