i think I have it dialed in..i can embed the image as a direct link at almost any size- i am setting it at 600x800 because it seems that will fit most people's default settings and loads fast enough AND the best part, if you want to see more, you click and it takes you to my, paid for, ad free, flickr so you can look at the full 50" image!!!!
i am with SP, i love the detail, like on the wild willie flower above you can see the ant!
