Not sure what you mean but I think your asking how do you post your flickr pictures to this forum?
Sign in to your account then click the photo you want to share. Then hit the "All sizes" button above the photo. You should now get directed to a page that list the HTML code and URL link for that particular photo. Copy paste either the HTML or the URL link. I recommend you copy paste the HTML because all you have to do is paste it to a post here and that's it. The photo should automatically show up in your post.
IF you copy the URL link you have to do the whole thing to get your picture to show up instead of as a highlighted link.
I hope this is what your asking? If not let me know and I'll try to help you out.
