Sorry guys. Maybe take it up with one of the moderators. It's not worth it in my eyes when some people interpret suggestions as arrogance and lay in to you for no other reason than that.
Nothing wrong with putting up pictures if asked to do so by others, especially where it could be of help.
I think the reason people take offence by your pics is because there's always a shot of your van in the background, or the picture is always taken from a distance to show the 'scale' of the job.
A few of us have been guilty of it from time to time, including me. It's a good feeling to pick up large jobs, it gives you a sense of satisfaction and being typical guys we like to find a way to gloat. 🤣
Maybe you could be a little more 'selective' with the pics you post, for example in this thread, you could pop up some up close pics of the gutters you mentioned, before and after.
