you can upload directly as an attachment to your post as well but you have to watch the size
you need to be in full reply mode, not quick reply...
if you scroll down you'll see an 'attach files' box...then a 'manage attachments' button... hit that and you can upload from your PC there, assuming it's within the prescribed limits of size...they're pretty small.
