Get the URL address of the image from the Internet by 'right clicking' on the image and looking at the image's Properties.
Just slightly above your own MoneyAM 'Add a post to this thread' box you will see a little tool box picture like this:
After you have Copied your image's URL address, then open this tool with a left click and insert the URL into the box that will appear with a Paste.
Another Left Click will deliver all the HTML script from the tool to your cursor's position in the 'Add a post to this thread' box.
Then just finish the post off as normal.
Don't forget that the image has to have a URL address. That means it has to come from some web site or other and not from your own computer.
Also, don't forget that if you mess up then you can use the Edit facility (it looks like this:

) and edit your own post after it has been posted.
PS. During the using of the image tool process you might have to tick to allow the use of Scripted windows.
And don't be frightened of trying it out! Print these instructions out and give it a go. If you mess up, then edit it all out and just start again.
