Ive had the same problem on a number of occasions now Gus, the file size from most image sources is to large for the forum directly.
The solution I came up with was to select all the pics I want to post to the forum and email them to myself. Your email client gives you the option of resizing the image before you send, so I select small. Then I just choose the file I want from the received email and that will post straight to the forum without using a third party host.
Great report Jeff. I was waiting for the accommodation story at Ceduna to end with one of you climbing in an abandoned bed of a recently departing truckie (like LTP and Fatman) but I'm glad that drama didn't play itself out for you. Well done.
