what are you talking about?? you can upload them straight to twitter..

everything is done right there from the console.

click share... choose twitter or facebook.. type your comment/hashtag... check who is allowed to see it... public, private, etc... then upload...

from there once it's on twitter or facebook you can do numerous things... like add to your imgur account or take into some photoshop program and alter the photo even more..

but I mean once the photo is uploaded from the PS4 to twitter or facebook, it's on the internet ready to be viewed by whoever stumbles upon it.

from there simply copy and paste the twitter link and post on reddit or do whatever you want with the photo..

you don't need all that hassle of putting a USB drive into a PS4 and copying the photos and then putting the USB drive into your computer and saving all the photos onto your HDD.
