I have attached some screen dumps in the Javadoc comments of some of my Swing classes and I would like them to be visible when hovering the mouse over the class name. 

```
/**
* The panel containing so and so... <br>
* <img src="../doc-files/ThisPanel.png" width=200><br>
*/

```

As there is little text in the description, the initial size of the popup is very small and it must be resized to view the whole image. 

Is there a way to have the popup contain the image or at least define its initial dimensions?
