If they aren't posting the codes, then all you gotta do is, when you upload the image, copy past the link to your uploaded image:
http://i.imgur.com/6H3zPFE.jpg
And then put these tags around it:
[ img ] [ /img ]
Without the spaces. Also if you just press
this button and insert your link it will put the tags for you.
and bam

My imgur still gives the codes though so I don't know what's up.
