the image problem was being discussed today in the shout box so that's probably why you couldn't, anyways I'm very excited to hear there's a single player mod in the works since the multiplayer maps I've seen from you are amazing so I can't wait to see what you come up with for SP : )
You can simply copy and paste image files into your post, assuming they're in a web format. Otherwise upload the image elsewhere and then post an image link.
On topic: Always happy to hear about more single player content in the works.
