I have an HTML5 application that allows users to drag-n-drop an image to a canvas, or alternatively, browse for it on their local disk. Once I got the image, I display it in the canvas using context.drawImage(). Got all the kinks out and it works great.
BUT. Now my customer want to use it on an iPad. Drag-n-drop is out of the question (the browser is a full window on iDevices). But the browse functionality, which is basically an input of type file, doesn’t work either.

To clarify, the behavior I need is selecting an image from the gallery and displaying it in a canvas.

Any ideas on how I can achieve this?

Thanks for your time.

    Unfortunately, there are no satisfying answers for this.

    Basically, mobile safari is pretty severely sandboxed – file uploads don’t work, can’t grab files from photos, etc.

    With iOS 5 there may be a solution for this using iCloud. Content is stored and pushed to mobile devices. Perhaps you’ll be able to access the image from your photo stream?

    Alternately, you could use a service like photo bucket or flickr to store your images, then use the API to access them from your page.
