The community rules say no pictures and I will always abide by the set community rules.
I cannot argue with your reasoning of possible better discussion without pictures.
My motivation was purely how to grow the group. Many go through the general feed on Lemmy. And I figured a relevant picture to a question was more likely to catch attention and increase participation and subscribers.
Unless you and the other mods decide to actually change the rules I will no longer make any posts that feature a picture.
I hate people who are new arrivals (me as a mod) who try to impose their opinions on the others who started and built the group. So I will abide by any decision that is made.
