I have done my fair share of ribbing people about pics, but I only mean it in jest.
Nowadays, I rarely create a thread when I cook something because...
1. I don't want to take pictures of it, I want to cook and eat it.
2. I see no particular reason to share the cooking session because it contained nothing new that I could "enlighten" people with. I've already done it before and posted about it. (use the search feature or ask)
Now, when I was new to forums I wanted to share every experience, many times without pictures. Back then, pics weren't required, but I would take them sometimes when I felt it important in helping people understand what I was doing exactly. People that are new today should be able to express themselves the same way.
My 2 cents anyway.
