"By the way, how can I post a Image without being a link that only logged in ppl can see it? "
Hi LauriPaul. Welcome to MLP. Each account on MLP has a place to upload photos. Just look under your "User CP" links for "Pictures and Albums". I upload my photos there and then just provide the link in a post using the "Insert Image" icon in your post editor. Many people use external photo sites but I've found the builtin is so much easier. Hope it helps. GitFiddle.
