Hi,
I've installed free Simple Image Gallery plugin (plugin_jw_sig-v1.2.1r2_j1.5) and it works great! I'm not familiar with coding  ??? so does anyone know how to make thumbnails to show without border and with reflection effect like demo on page  idoitforu.com/extensions/80-module-cpg-high-slide-lightbox-with-reflection-effect.html#Demo
(Demo: joomla15x.idoitforu.com/)

Thanks for any response
Oskar
