TechCrunch are reporting that the next version of Apple’s OS – iOS5 – will have Twitter integration built into the OS for photo uploading. Twitter are looking to launch their own photo-sharing service, aimed at cutting out the various image hosting companies such as TwitPic and yFrog possibly using the twimg.com URL “that Twitter has used internally for a long time”.

We’ve heard from multiple sources that Twitter is likely to have a big-time partner for such a service: Apple. Specifically, we’re hearing that Apple’s new iOS 5 will come with an option to share images to Twitter baked into the OS. This would be similar to the way you can currently share videos on YouTube with one click in iOS. Obviously, a user would have to enable this feature by logging in with their Twitter credentials in iOS. There would then be a “Send to Twitter” option for pictures stored on your device.

With Apple about to announce the features in the new iOS5 next week, Twitter will need to get their own photo service up and running asap.
