I'd like to use a mobile device's camera to capture an image and then upload that image as a feature attachment. No problem getting the image from the camera. I create an <img> tag, and set the src to be a data URI, and show it on the web page in a gallery. Once satisfied, I'd like to upload each image as an attachment to the selected feature. They're obviously not stored on disk, so how can I upload the images when the API requires that the attachment be specified using a file upload field in a form?
Appreciate any insight!
