Imgur

If you have used Reddit, then you will have heard of Imgur. For a good long while, there was no way in which you could upload your own images to Reddit. You had to use external hosting services, and then just link them whenever you made a post. Obviously, this has now changed, but Imgur still thrives.

Imgur is (mostly) an image upload service. It boasts a ton of other features, but if you want to upload images in a gallery format, or even just a single image, then you can do that in no more than a couple of clicks. You can then share the link you are given with whoever you want.

If you are on the hunt for a good bit of porn, then this is one of the best adult image hosting sites for that. There is a nifty little search bar that will allow you to search through a ton of different tags. Various communities have grown up on the site too, so you can even interact with them with regards to image sharing.

All in all, this is a brilliant site, and probably the first image host you should be using. Although, do bear in mind that everything uploaded here can be seen by everybody else! There is no private link sharing.
