Posting a photo is pretty simple and there are a couple of methods:
1) when doing a reply, the Fast Reply form at the bottom of a post does NOT contain the utility link to upload a file/image. (I guess that's why it's called a fast reply.) If you want to reply and upload a file/image, click on the Post Reply button just below the lower left hand corner of the last post on the page. (You can also click on the Reply or Quote button on the right side of a particular post if you want to reply specifically to that post or quote that post). This will bring up a Reply to Message page. Just below the space where you type your reply, there is a link that says "Click here to upload images and files!" It will open a dialogue box and you select the image/file (only jpg, gif, and txt files are supported - max file size is just over 200K each). Once you've selected the file(s) off your computer, click OK, the dialogue box tells you it's processing the file(s) and gives you a confirmation that the file(s) are uploaded (or not if you exceed the file size). Click OK again and the dialogue box closes and you return to your reply.

2) if the photo you want to post is already posted somewhere on the web, you can just insert a "image markers" using the image button that appears in the Reply and Fast Reply area just above the space where you type your reply. Clicking on the button inserts the following characters (image)(/image) except it uses square brackets (which I didn't use here as the site would think that I was trying to post an image right now). Then reposition your cursor and paste the URL for the image between the margers such that it looks like this:

(image)http://www.cas2.com/images/JAS39Gripen_000.jpg(/image)

When you click on OK to post your reply, the reply will include web image at the same size as it appears in the source page which is why you sometime see very large images posted. Incidentally, the URL in the above example is for the photo below. Good luck with your turbine issue.
