I don't know about Imgur, because I use photobucket. But photobucket has a mobile app that you can upload pics directly from your phone to the app, then copy the IMG file in the app and post on your thread here on TG. I have mine set up where it automatically gets my pics from my photo album and downloads them. You can also take a pic directly to photobucket with your phone. Just always remember, if you delete a photo on the image hosting site, that photo will also be deleted in any forum it was posted in.
Like anything else, it seems hard when you are not familiar with how to do it, but then easy once you do know how to do it.
