Loading images in html in a QTextBrowser

Hello all. I am trying to load some simple html into a QTextBrowser and display images, but the images do not load unless I specify the full path to them. I am loading the html with the following:

QTextBrowser *textEdit;
...
QFile file(fileName);
textEdit->setHtml( file.readAll() );

This came from QT's QTextEdit example but I changed it to use QTextBrowser instead of QTextEdit because I want links in the html.

The following html correctly displays the image:
<html>
<img src="d:\1.JPG" />
</html>

The following html shows an image icon instead of the correct image:
<html>
<img src="1.JPG" />
</html>

The image file is in the same folder as the html file. Any ideas how to make this work without providing the full path to the image files?

Thanks
