I tend to use dropbox to distribute a photo to my friends over IM. When I put it in the public folder, I can share it, but if I drop it in a photo album, I have to choose between pointing my friends to the entire album or choose:
Browse on Dropbox Website -> Gallery View -> Maybe click the right photo in the album because the web view doesn't always choose the right one -> Right click -> Copy Image Address, and then paste it into the IM window.
My suggestion: Right-click the file in the desktop or mobile app, choose copy link, and then get a link like https://www.dropbox.com/photoshow/Bos... that works without logging in. That way, the recipient gets to see the picture I want them to see right away, and if they're interested, they can keep browsing through the album it's in.
