>how do you put a picture in a forum message

the picture you want to use has to be somewhere on the Internet already.

I'll describe the steps to help you do that.

in a different browser window than the one you're viewing this forum with, upload your chart to an image hosting site (such as postimg.org).

make sure you copy the "Direct Link" address it gives you, you will need that link information for the next steps.

OK now you have the graphic you want to use hosted on the Internet.

back on Agoracom, in the bar above where you type in a new message to post, you will see a green icon that looks like a tree:

click that icon, to open the picture insertion window.

paste in the Link information from postimg.org that you copied to your computer's clipboard during the earlier step.

select Insert, and the image will be added to your post.

hope that helps.
