If you have a screenshot you want to be shown, you can post it to some image hosting site, like

They will provide you a sample code to copy-and-paste here. No account needed, so it should be trivial to do.
For example, to get this result....
If you click on the image above, there is a line that says "Forum". Copy that and paste it here so you get a thumbnail image that will open full-size like the one above.
