Here is another way to attach pictures - using the "manage attachments feature below the "reply to thread" or "create new message" boxes.
See the thumbnails attached here - those show the four steps to uploading a picture.
1. first you click on "manage attachments"
2. Then you browse on your computer to find the picture you want to upload
3. Then you select the picture you want and you will see it in the "browse" window.
4. Click on the button that says "upload". You will then see the pictures attached as thumbnails. People can click on them to see the whole thing.
There are four attached thumbnails below that show this. Each attachment goes with the four steps above.
