This should do it-
Jim- I can't edit your post to show the pic, so I copied it and posted it here.
Easy to do. We'll assume the picture is stored on the hard drive of your PC.
1. click on "embed picture in post"
box at bottom of window where you compose a post.
2. Click on "upload picture"
3. Click on "browse".
This will take you to the directory for all of the files on the hard drive of your PC. Find the pic you wish to post and "double click"
4. You will get an "uploading" message for a few seconds and then it should say "file uploaded successfully". You're done. Complete your post as usual.
Give it a try and post any questions you may have.
