Swallow: I looked at adding a couple of pictures, but the tool button seemed to want a URL link. Is there another way?
Depending on what control you want over the pictures....
I don't know if non-full-members can upload direct to the site, so I can comment well on that.
When doing a post there is picture button at the top with what looks like a picture of a tree. FMs get two options for upload either "from computer" or "from url". I don't know if members only get the URL one.
What (I think) most people do anyway is set up a photobucket account (free) and use the URL option. e.g.
http://s1059.photobucket.com/user/swallow-bcuk/profile/
Copy the URL for photo from photobucket by going to the picture in photobucket.
At the side it says "links".
Click on the one called "Direct".
It'll say "copied".
Then paste that into the URL link on the photo upload dialogue box mentioned earlier.
Untick the box that says "retrieve remote file and reference locally".
Then hit OK.
With that you get full sized photos as part of the text like this.

If you used the "Go Advanced" option when editing a post it also gives you a preview post button so you can see exactly what your post will look like, including any embedded photos.
Going with the upload to site option would make the pictures small and they need to be clicked to open up to bigger (but still not as big as the URL to photo hosting side/skydrive/gmail drive/whatever.
