With Android it is easy. If you have a gmail account you also have all the other benefits such as photos (picassa). You can upload to your photos directly from your phone, open "photos" in a browser on your laptop, tablet or PC, find the pic and copy the url. I like to "open photo in another tab" because it displays only the photo.
I have multiple google accounts but for simplicity's sake I only use a main one on my Android phone and stay signed in all the time. Even better is to use Chrome and sync across all your devices- even the Windows based, but that's another topic.
