In Outlook, adding a graphic or animation (an animated gif, for example) to your signature is as easy as adding a picture to an email you send.
Insert a Graphic or Animation in Your Outlook Email Signature
To add an image to an email signature in Outlook:
- ›› Step by Step Screenshot Walkthrough (using Outlook 2003)
- Create a new message in Outlook using rich HTML formatting.
- If you want to edit an existing signature, see below.
- Design your desired signature in the body of the message.
- It is best to keep your signature to 5 or 6 lines of text, but not much more.
- Use the standard signature delimiter.
- Position the cursor where you want to insert a picture.
- Use Insert | Picture... to add the image or animation.
- Make sure the image is a GIF, JPEG or PNG file and not too big. Other formats such as TIFF or BMP produce files too big. Try reducing the image size or resolution in a graphics editor and saving the graphic as a JPEG if the image file size exceeds, say, 150 KB.
- After inserting the image, you can highlight it and add a link, for example.
- Press Ctrl-A to highlight the entire body of the message.
- Press Ctrl-C.
- Now select Tools | Options... from the main Outlook window's menu.
- Go to the Mail Format tab.
- Click Signatures... under Signatures.
- Click New....
- Give the new signature a name.
- Click Next >.
- Press Ctrl-V to paste your signature in the Signature text entry field.
- Click Finish.
- Now click OK.
- If you have just created your first signature, Outlook has automatically made it the default — automatically inserted — for new messages. To use it for replies as well, which I recommend, select it under Signature for replies and forwards:.
- Click OK again.
Edit an Existing Signature to Add an Image
To edit an existing signature using the method described above:
- Select Tools | Options... from the menu in Outlook.
- Go to the Mail Format tab.
- Click Signatures... under Signatures.
- Highlight the signature you want to edit.
- Press Ctrl-A.
- Hit Ctrl-C.
- Use the Esc key three times.
- Create a new message in Outlook using rich HTML formatting.
- Click in the body of the new message.
- Press Ctrl-A.
- Now hit Ctrl-V.
- Proceed as above. Instead of creating a new signature again edit the existing.
