Or other websites that "banned" JUB
be sure not to copy their "forum" code just, the link to your pic. anything with [img] etc will NOT work. You just need the URL
http://www.domain.tld/user/pic.jpg
this url is automatically made clickable from the forum - this will NOT work for most users, either. so just post the URLs in your post, then scroll down and below the "submit thread"/"post reply" button there is a checkbox labeled "Automatically parse links in text" UNtick this one, and click the submit/post button. after that it would look like this:
http://www.domain.tld/user/pic.jpg
It works this way, but that way users are forced to use copy&paste to view your pics, which is a bit of "work"so if you want to reach more people, you should upload the pics in your JUB gallery, or post them as attachments.
