Yep Dropbox or Google Drive.
You can set up either to just auto-upload any pictures you take with your phone, and obviously you can send other file types to it as well.
I have both Dropbox and Google Drive on all of my portable devices and computers.(My work computer for some reason doesn't like the dropbox website, but I can access Google Drive fine otherwise I'd probably just use Dropbox exclusively)
They're great. For my job I have to take pictures of houses almost daily, I can go out, take 10-20 pictures with my phone and they're all waiting for me on my computer ready to go by the time I get back to the office 5-10 minutes later.
