NRW posting photos

would someone mind explaining to me how you post photos or are we even allowed to post them. I have tried copying and pasting but with no luck. I also tried the Img button but it did seem to take me away where, nor would it allow me to insert and paste. The img is on to the right so somehow it must be capable of being done.

Mark,
If the photo's within the size limits - there's a tab below in the post thread/reply window that says 'upload attachment'. Hit 'Browse', select the picture, then Add file and place it inline to show it in the photo.
Alternatively you can go to a website such as imageshack.us or photobucket that hosts pictures - upload an image there, then paste the url to the image between [img]and[/img] tags.
