I have just been put on a trial for a job in design and was asked to design a email template with pics etc.

I have designed the template and it looks amazing but I am unable to send it to another email account with the pictures...
When I send it the background colours go through but the images dont send and you cant see them.

Is it because of the file format i am saving it in...
Do I need to save it as a CSS or something so that the pictures are constantly linked in to the template.

I also have the template but want to be able to add text after i have put it in a email...
This would allow me to use the same template more than once but with different text each time.

abit like this but more in depth...
