Earlier this month, TwitPic changed its terms of service. The changes allow TwitPic to use and sell your images without giving credit or paying royalties to you. If that doesn't sit well with you, Img.ly is an alternative service with similar features where you own the images you upload.
The changes that TwitPic made to its terms of service angered a number of its most avid users, and we mentioned it when we looked at the five best services for quick image sharing. Regardless of whether or not you use Twitter heavily, the service was a great way to quickly upload and share images. Thankfully there are plenty of alternatives, and img.ly has seen its membership grow in recent weeks as a result. The service has support in the official Twitter clients for Mac and iOS, Twitterific, Tweetbot and DestroyTwitter, one of our favourite Twitter clients.
Img.ly gives you a way to post your images, get a short link, and share it with friends. You can keep track of how many people have viewed the image, embed it on another site, and others can log in and comment on it. It's not the only alternative out there, but if you're looking for an image host that lets you retain ownership of your images and hasn't been swarmed with new users, it's worth a look.
