My sliced WordPress images have gaps

I’m trying to drop an image with three slices into my post. Padding is being added. I just want to get rid of padding for these three images and don’t want to mess about with css if possible. I have tried adding style=”padding-top: -10px; padding-bottom: -10px;” to my image tags, but it hasn’t worked. I’m using Genesis framework with Dynamik theme, for info. The page I’m having trouble with is this one: http://www.madetomeasurekpis.com/what-is-a-kpi-2/

Thanks!
