I was wondering if I can have some effect on an image of an article, that when I pass over there is a kind of hover effect that image fades a little and some text shows over the image.
This is not a function of rokbox thing. rokbox "happens" after you click on the link, what you want to do is to add a hover text effect before that.
I'd suggest that you consider using our roksprocket plugin to achieve that rather than coding everything in your article yourself. - have a look at the roksprocket demos.
Regards, Mark.
