Hello Sid,
I am not sure how to attach a photo. It won't copy and paste!

When posting a message, click on the 'image' button on the right side of the page. Select how you want it aligned (just select default as it's a pointless feature)

then it will open a window where you can put in the address to the location of the image.

The image has to be located somewhere such as Flickr or some other image hosting site. I use Imgur.

In Imgur or Flickr or whatever you use, there will be a sharing option that will give you a link. Copy the link and paste it into the image location address dialog.

Or, if the image host gives you a BBcode (as Imgur does) you can paste that straight into the message without needing to use the image button first.
