[TYPO3] WEC Staff Directory and image rollover

[Jogvan Olsen]

Hi List

Is it possibly to use image rollover in WEC Staff Directory?

What I would like to do is:
In the view 'list by 2 columns' I would like all the images to be black and 
white - when I hold the mouse over the image, it changes to color.

Is it possibly - and if, how?

Thanks in advance
