Here's a test and INSTRUCTIONS on importing images into a posting on this Forum.
First, I'm busy typing some text. Next I'll look just below this text box I'm typing in and push the Upload Attachment button (bottom left corner of the text box).
So next I browse my computer for the image I need, just like on an e-mail. Add a caption if desired, push the button and upload the image. Somewhere in here is a button asking you if you want the image in-line or not.
If "YES". some text with the image info will pop up where you left off typing. You can move that text around to where you need it. I did that for the image above by hitting "ENTER" a couple times to move it down a line.
Now keep on typing away happily till the next image need insertion.
There ya go!
