From what I see, as member, it is only possible to upload photos with a very small filesize (so a tiny picture) to the forum. Even then, they don't appear automatically and you have to click on a link.
From what I can see I think it would require either a substantial update or a new forum to allow all photos to be uploaded directly. Even if this route was to be pursued, the handling of an ever increasing number of photos would mean that the forum would need extra storage facilities as well.
Six months ago, to the day for obsessive types, I posted instructions for using a free photo sharing site that would allow photos to be attached directly to your post. The instructions are at #7541 of Today's bike ride.
It's easier and simpler to use than Facebook, and the technique I outlined will also allow you to attach a photo to an email - so it has other uses too. It's not difficult, but if anyone tries it and has problems I am happy to assist; anyone with a teenage child/grandchild should be fine!
