I recently started a new website http://www.lukestarlight.eu and chose this theme which I really like, but I can't figure out how to add custom pictures to the slider. I know I can add a featured content there, but (and btw. then it's just small pictures - thumbnails, which is not satisfactory) I dont want that. I wanna add pictures to the slider I choose - with no relation to post or pages. It must be possible since there are many themes outhere where it can be done -> e. g. http://smthemes.com/soundwaves/ (i tried and it's easy to do that).
Can anybody help me with this issue?
