In respect of posting of images, although I haven't seen any body get banned although I don't know if it's because I have search hard enough but I wouldn't want to be corrected by someone again through PM so I decided to come public on this one. So please the community should clear if I can banned or tagged from copying someone image in creating my topic without adding a reference link.
And please don't mind the English error as am trying to improve in my writing thank you all.
Simple answer yes, this is when you claim the owner of the image when you use it on one of your post. This is why you should put the source if you are using it as reference to the topic you created to avoid confusion that you are not the real owner.
But if you are just posting image just for sharing the content without any description on your post that expresses your ownership then you are good to go to post image without any source. Most of the time, image use on info thread is always subjected to copyright when doesn’t disclose the source it will looks like that you own it since the content is originally from yours.
