Normally, one uses the Go Advanced button below the posting entry box and the attachment tool - looks like a paper clip - to upload pictures here. Works fine on a Mac.
Problem is that tool is down at the moment. Admin is aware of the problem and is working on it.
When it's up again, we'll be sure to post back here and let you know.
In the meantime, you can upload your pictures to one of the popular photo or file sharing sites and link it in to your post using the image tool - it's a yellow icon with a sun over mountains.
We apologize for the inconvenience and appreciate your patience on this, hopefully the attachment tool will be back up soon.
