Hiya LynnJenny and Sue,
As you know I struggled with the posting at first

, but I realise now where I was going wrong

.
First Open
www.imageshack.us, and select browse.
Double click on the picture you want to post
Set the resize box to 640 x 480
Click Host it
Copy the box called Hotlink for forums(1)
Paste into the message bodybox on the posting page not the subject box.
Click on 'Disable HTML in this post' and 'Disable BBCode in this post' boxes so the tick goes off the small box
Then submit.
It was trial and error with me, but thankfully got there in the end

.
Good Luck
Debbie
