Thank you irwinsailor, I'll try to improve it as we go. Now I've opened some sections for image postings. You can actually have photos visible in the post by using the IMG-button.
The image must be located on another server to have a web address, but most people have some web-space with their internet
provider. If not there are others giving space away for free.
Doing it this way we will keep the database small and not too slow much longer - to the best for all of us.
