Thanks Alex. That’s a good one! You are right I have little experience in these stuff. but I have graduated as a software major and have been a software engineer 30 years. I spent hours searching for an answer and can’t find one. Is it my fault or the software you provided too (damn) hard to use???
Get back to my issue. I attached my screenshot. I am not sure what I see is the same as what you see. In the revslider editor/global layer/slide options/, you can see there is nowhere to change the background/source picture. Is it because the revslider version I am using is limited?
For now I tried to hack the code, replacing bg_11.jpg you are using with my intended one. It shows in the revslider, but not on my website. I flushed cache.
