but for the second part of vbexperience, I was not understood the change has done, in which part is located t'elle? please
I have no idea what template it is, but I would guess the postbit one (which may call another template, I don't know). It's the part of your code which spits out the images for your hack. It could be in a plugin though. I have no way of knowing. You just need to find the code that spits out the three images for each of those bars.
