I apologize in advance, this is probably a dumb question, but I want to be sure in what I am doing. I am about to upload my first ever project on Videohive, and when uploading there is a request for including a thumbnail. My friend, who also makes money on envato but on audiojungle, told me that this is just your logo. But I am still not sure, is it really just a logo or a picture from your project? Would be great if someone could clarify this simple thing for me.
