The details of iOS 5 should be laid bare this coming Monday, but some snippets are still trickling out, including an interesting little piece relating to Twitter.According to TechCrunch, Twitter is intending to bring imagery 'in house', as opposed to leaving it to the myriad of third-party sites out there. So rather than upload to an external site, which publishes your photo on micro-blogging site, you'll upload to Twitter, which will offer a short link and perhaps a thumbnail relating to your image. Not a lot different – perhaps a little speedier though.For Twitter, it works because it brings the service under its direct control and probably offers a number of commercial opportunities too, not least some potential advertising gains. But it also means it can work deals with the major mobile manufacturers to embed Twitter more deeply into handsets. The first of which is likely to be Apple.TechCrunch claims that Apple’s new iOS 5 will come with an option to share images to Twitter 'baked into the OS'. It would be similar to the way you can currently share videos on YouTube with one click in iOS. Presumably, you would enter your Twitter account details in settings, so when you need to upload an image, it really is seconds of a job - just pressing 'Send to Twitter'.There's also talk of similar speedy uploading being built in for Facebook and Flickr, which might also be showcased on Monday at the WWDC keynote speech. Not long to wait to find out.
