Here's a few things I have learned in my noob status. You may want to resize the image so they don't take so long to load. I use 800 wide, but you can experiment with what you like on the "Test forum." Also, you can insert the image rather than show as an attachment if you like -- this is simply a matter of preference. To insert, simply click on the "insert image" icon.
I would have demonstrated this with a crop iof your grebes, but see you do not want your shots edited. Lee
