Hi John,
At the bottom of threads there is the post reply Text box, (First attached Pic)
Blow the Text box are two clickable buttons, you want to click on the "Go Advanced".
(Then you are confronted with the screen on the second Attached Pic)
Below the Text/post entry box you will find the clickable button labled
"Manage Attachments"
When you click that button, a separate screen appears(Pic#3)
Click "Browse" to find your pic that you wish to attach, then click "upload"
Once pics are uploaded the window looks like (Pic#4)
When you've uploaded your pics click "Close this window"
Then you can submit your post/thread and the attachments will appear like Majik.
Hope that made sense. and helped?
Mike.
