Kevin correctly understood the essence of the problem: your URL on your main page most likely refers to the location of the main page, and when it is included in the child page, the relative link no longer works. The simplest solution for this kind of thing is to have your main page URLs relative to the site, not the page. In other words, if you did
<img src="images/picture1.gif">
You need to replace this with
<img src="/images/picture1.gif">
or something similar.
