Thanks for bringing this post back to life @Panda. I would have thought there would be mods to moderate any inappropriate pics. Generally if you place an inappropriate pic there would be a warning or ban of some sort. Most should know the rules of posting like in many forums. It's 2021, has there been no progress?
Just as an added feature, how about allowing the customer to customise their profile pic, allowing gallery pics. Or is the reason it's tied down (restricted to AGL's gallery option), is to avoid customers placing inappropriate pics?
