Pretty sure no matter what device you use, for the most part unless you resize and put your pics into the gallery you're going to have them hosted somewhere else be it PBucket, Facebook or some other third party.
For what it's worth I did try Imgur yesterday and it seemed pretty straightforward. Uploaded and before saving anywhere if you click on the image it says something like "links" on it and you can copy the IMG link and then close it out. It was just for a screenshot of an error I was getting on here, not sure I'd want to put personal type pictures up there for all to see though.
