Q: How do I include images in my signature?

You will need to upload your image to a place on the web that anyone can access and point the src="" tag to that location. For example, I uploaded my logo to http://blankcanvasweb.com/skins/blank_canvas/images/bc_logo_75.gif, so the HTML code for my image is as follows:

<img src="http://blankcanvasweb.com/skins/blank_canvas/images/bc_logo_75.gif" />

The important part in your case will be the src="" tag.  A good question to ask yourself is "could I get to this image from any computer?". If the answer is yes, then you're in good shape.

You can include some additional formatting to help make sure that your signature will be correctly laid out even if the image is not displayed:

<img src="http://blankcanvasweb.com/skins/blank_canvas/images/bc_logo_75.gif" style="float:left; width:75px; height:75px; margin-right:10px; border:none;" width="75" height="75" alt="Blank Canvas" />
