I installed Inkness! Seems promising to my purpose. Actually I couldn't add a slider. In the options theme, slider tab (Slider settings), I checked the box named 'Check this to Enable Slider' and add some figure with text. Unfortunatly the slider didn't show up!
I have to make some other stuff to make it works?
I have already changed the settings/reader to the homepage as a static page.
Thanks for your support!
