Images overlapping divs

[AdRock]

I have a class div which is designed to have an a small image floated to the left and some text next to it giving a description of what the image is.

The problem is that the image is overlapping the div whereas the text fits perfectly. I have placed the code for the image source within the <p> tag to conform with XHTML.

I can't set a size for the height becuase I don't know how much text or how big the image is going to be and I need the div to resize if the user increases their text size (i'm trying to make the site accessible)

This is the CSS

p {
   font: 80%/1.8em Verdana, Geneva, Arial, Helvetica, sans serif;
   padding-top: 0;
   margin-top: 0;
}

.contentbox {
   height:auto;
   font-size: 80%;
   clear: left;
   padding: 2px 4px 2px 6px;
   margin: 0 0 10px 0;
   border: 1px dotted #B1B1B1;
   background-color: #F4F4F4;
}

.contentbox img {
   margin-right: 5px;
   float:left;
}

and finally an example of my div

<div class="contentbox">
<p><img src="images/traditional-souvenirs.jpg" alt="Souvenirs" />

Specify the width/height of the image:

<img src="images/traditional-souvenirs.jpg" alt="Souvenirs" width="25" height="30">
