image is not appearing with email

I am sending a html table with an image of google map.for mozilla Thunderbird image is appearing without any problem.but for gamil and yahoo mail image is not appearing.even a broken image.is there any reason for that? here is the image tag I attached to the table

<image src = "http://maps.googleapis.com/maps/api/staticmap?path='+startCity+'|'+dueTodrawPath+endCity+'&size开发者_C百科=500x200&maptype=roadmap&sensor=true" />'

shouldn't it be <img src="" />

<image> is not a valid tag, you should be using <img>
