I wanted to show everyone how to post images and photos to the forum.
If you're posting a new topic or replying to one, you should see a button labeled "Add image to post" at the bottom left of the text field:

This image above is a thumbnail of the image, but you can click it to see a larger version. You have the option of displaying a thumbnail, or the full version of the image.
This method allows you to upload an image to the board.
Using the other method - from the image icon at the top of the text field - inserts [image tags] which allow you to link to an image hosted somewhere else.
You can use either method, but I prefer the first one - Add image to post.
Hope this helps!
