You don't. It's not permitted.

 

OK.....so how does everyone else do it? I know they attach a link or something. But I need to show some guys my heads and get a few answers..

Put the picture online somewhere through a picture or web hosting service. There are a few free ones out there or use some free space if you ISP gives you any.

Then, just post a link to the image. If people want to see it, they will click the link.
