I don't know anything about this site but I would post pictures of it if I could
Looks like you were able to attach the pictures (very interesting photos).
For anyone else who ever wants to post a picture you can click on "additional options" below where you type your message post. There is a spot that says "Attach" that you click onto and then "Browse" to find your picture from your computer. From there you can upload your photo. I believe when you do it this way that only members who are logged in will be able to see your photos.
If you post your photo to an online hosting site as member OneandOne mentioned then the image will appear to everyone even if not logged in. You would post your photo into your message in a similar fashion as the following example:
// img src="http://www.website-address-used.com/image-name.jpg
Note: Do not include the // on the ends of that code. Those were included only to make the example code visible.
If you try this method and have any problems just let me know and I can help you out or I can even upload the photo to this website...
