I think this is it ...Actually at the top of the reply window there are some things to use for links etc. I actually forgot how to have a picture show in the thread; John??
1) go to your picture that you've uploaded into the MSA gallery
2) "right click" on the picture and then you should see something like "copy image location" - left click on that
3) when you make your post here, and when you're ready to insert your photo, click on the icon above the post writing window (second from the right) that looks like two pyramids
4) put your cursor in the entry bar, right click and then click on "paste" and the location of your photo will be displayed like this sample http://www.apug.org/gallery/data/508/Be_considerate.JPG in the entry bar
5) click on "OK" and you should be set
Here's a try ::
I hope this isn't too confusing
