Image in checkbox description

Hi everybody

i want to put an image into a checkbox description. I’ve done it like the example in the book of vaadin:

checkBox_1.setDescription("<img src=\"../VAADIN/themes/style/img/Info.png\"/>

but the image is not shown.

My project structur is like this:

src
-main
-java
-foo
-bar
Test.java (The Checkbox is here)

The image is in my theme folder: src/main/resources/VAADIN/themes/style/img/Info.png

What i do wrong?
