Congratulations! To upload pictures, just click on the icon in the upper right (when you are in your reply or thread starter) - it is not the paperclip icon for attachments, but 2 to the left next to the filmstrip. It is the icon to 'insert image', then you can browse your computer to insert your photos. I finally, after several mistakes and misposts, just figured out how to reply to a message with the original still in it and to reply to 'multiple quotes.'
Enjoy your new babies!
