You will be able to preview them properly if I’m right, but once you publish the post, the images won’t display for anyone until you yourself become a Jr. Member (you need to earn at least 1 Merit at this stage, since you already meet the Activity criteria).

Note: I checked your posting history to see if there were any posts that could postulate to earning merit. Alas, all the posts are essentially self-centred bounty related, so no real option so far.
