It appears nobody has actually explained to him how to post screenshots on the site.
To directly put it onto SEN, click the Browse button and find your picture. Then click the Add this Attachment button. The page should refresh, but it will show your new attachment. Then hit the post button.
To use an external link, upload it to a site like
imageshack.us It will tell you to copy and paste some text into your post to display the picture.
