So are you unable to just directly post links or to upload images via the forum attachment system? Because if you're referring to the first possibility, then that's normal since you don't have the minimum required post count in order for one to be able to post links yet, which is 15 posts. If that's the case, then just post the links in the following way: www . mpgh . net, (with spaces in-between them), until you achieve it. Otherwise, I've no idea. As far as I know, you should be able to upload any image you want regardless of the fact that you're a very new forum user.
