okay here is a way to do it. when you look at your photo , right click on it. you will most likely see something along the lines of "copy image URL" click that. now you should have something that ends in .jpg A good way to test it is to Paste (ctrl + v) into the url spot of your browser. then go to the page. if you see *only* your photo, no background no frames, then you have the information you need and can put that inbetween the [url brackets.
Feel free to PM me if you need more help... I don't always explain things well, but I can get it done. (even if you link me just one of the url's for a photo, like the 'share' link. I can then go about telling you *exactly* how to share it. sometimes you have to inspect element, then look for the .jpg (which is what I do with facebook)
