Op is of newbies rank, so he can't add images to his post for now.. op, you need to be at least of a junior membership to enable images then upload to an image hosting site and post the link to display here on the forum.. or you can get a copper membership as well to enable you post images...
OP does not need to buy Copper Membership. His profile has enough merit to be promoted to Jr Rank. He has 26 activities and by posting 4 more to make 30 activity on his profile, he will become a Jr Member. then his image will be displayed.
This is true but I think Hatchy only just want to let the OP know about copper membership also and not advising him to get a copper membership. OP can wait until he gets to 30 activities but he can start uploading the image now so that when it has the required activities, the images will automatically be displayed.
