So I have to click multiple links to 2 year old threads to find the rules of any of this type of thread?
My mistake, I guess.
No, it's just a rule.
The soft line is, now you know, just adhere to it, no point arguing about it.
The hard line is, ignorant is not an excuse, just do it.
Either way, it's the rule and it makes sense. If it weren't there, people would be just posting Google images or Amazon images, then you ask yourself what is the fun in that? The images does a few things
1 - often it shows scale
2 - it shows what it is like in person, a lot of stock photos embellish how good an item is, at the end of the day, it is its purpose
3 - not so much here, but it shows ownership. It removes the little chance that someone wants to brag when they have nothing to brag about. We hate that.
