Hello, I just want to ask one thing. I am creating a game and just for purpose of placeholder I use some random images from the internet, just to see the overall feeling and atmosphere. I am aware that is is not possible to publish a game with pictures or any content that is protected by copyrights, but if I am using it as a personal project and it is just for personal training purposes, am I able to share it for example here? I want to get some feedback before I will change the pictures for my own (it is very time-consuming to produce them) and with empty picture frames, it will lose a lot of its atmosphere.
So, is it legal to upload a game like that to this site, or any other if that suits just for my training purposes and not commercial?
