header highlights

Hello Skandha,   I want to use the header highlights. The header highlights in total is too high for our website. I thought it should be possible like on the website toerfietsleusden.nl using the theme catchmagpro. I think the images cannot be smaller than the prescribed measures. That is why I want to use the possibility to have only three images. In the header highlight part of the Travelore theme the theme let me choose for three images. After storing the website the middle image stays big. You can see it on www.staging.toerfietsleusden.nl. Is therefore a solution? Kind regards Hans Hagmeijer
