Okay.
So, I don't know what is going wrong with the links to the folder for you, but I did figure out how to post the image. If you go to the image on your dropbox site, you can't use the url at the top of the page, but, if you right click on that image and choose "view original," then it takes you to the original image. Right click on that image, and choose "Copy Image Location." Paste that here using the "Img" button above and it works. The downside is that your original image is huge, so it looks ridiculous here. I've shown an example below. To see the whole image below, one must right click on this image and choose "View Image," and then you get the whole pic filling the screen. The bike definitely looks in need of more than a bit of TLC.
