I'm prototyping an iPhone app for an acquaintance and there's a requirement to share an image between devices. I'm thinking of the easiest way to do this. I know that on an iPhone I cannot send mail or text messages without user approval and I do not have a web server or server-side scripting knowledge. This leaves some third party image sharing service.
Are there any iOS examples out there on how to temporarily upload an image to an image hosting web service (flickr, imgur?) and get a URL to the image back? Ideally this would not require a login/password combo and can hold images for 48 hours or so.
You could use the Imgur API which is free as long as you're not planning to make money with your application or your application is an open-source project. It allows you to upload your images with ease.
