Hello! I found myself in the same postion as you a few months ago and some very nice person send me these instructions, so I am happy to share them with you. Go to this link (the very first post on the home page) and scroll down to 'Tutorials'.viewtopic.php?f=1&t=10
You should be able to upload your pictures after reading this information.
Of course, I chose to get a free membership to http://www.photobucket.com
I create different files and upload pictures there and then copy the link for each picture and paste it in the message here. Everyone will have access to your pictures directly.
Hope this helps and you can get lots of information.
