At the bottom of the post page you will find a "manage attachments" button. Click on this and then browse for the picture on your pc and click upload. If you just post one picture it will show up in your post. If you post several pictures they will only show up as attachments. Click on post and then go back in and edit it. ( I find this easier) just click on one of your attachments it will be displayed in a new window, then copy that url (address bar) then click on the button Chad pointed out and paste the link in there. Ctrl c to copy and ctrl v to paste or you can right click on the mouse toohow do you post pics?
