I came to look after seeing a chat from Hive account@chhaylin :-)
Personally, at this point of time, I'll think video is not as popular here yet. I'll suggest you have some photos. It's important also which photo you place as first in your post because it gets displayed into the summary. I'm still figuring things out and sometimes even edit to change the position of the photos to the first after a couple of hours. It not easy to figure which works but I find some picture even if you make your own simple graphics if relevant seem to make a different.
