the site has a feature where you can attach pictures, however i have a photobucket account and upload to there. you can get the code to post your image and just paste it into your reply.
If you want to become a member I suggest using the right categories instead of making a mod do it for you.
As far as right from the phone to the post, no. It's just like everything else. However, if you wanted to upload it as an attachment, you could do so.
That being said, junior members have limited space allowance and you may only be able to upload a few pictures before you can't upload any more.
