Trouble Posting

[DgoDave]

Trying to post my SM for sale but by the time i type the listing and attach the pics the site tells me I'm not logged in. Been through it twice so far.....
Got it up but pic just show the IMG_4293.jpg not the image

Why can't I post a picture with my screen name?
I'm sure the answer is the same for why I can post pictures in the reply box?
