thx for reply. I posted my image with some of struggeling out. But I made it. Problem was when I tried post image with URL to Steam. When I moved image to imgbox.com (and used URL from imgbox.com), it worked fine. With creating post with Steam's image, progress bar was showing "saving ... ". After that, there was no notification about some Error, and my post was somewhere, "nowhere". So I created new post only with text without image. It worked fine. Then I tried to edit my post, and put there img with URL to Steam. Result was similiar. Content of my original post was deleted and post was shown as blank. Way to post it succesfully was to use imgbox.com I know that this post is off-topic, so after reading you can delete it.
