[Feature Request] Send content to Summit to use later

I know there is already a feature that allows you to send an image to Summit to create a post but sometimes I want to reply to a comment with an image and I don't want to use the janky Android image picker to find the image. It would be cool to be able to send an image or maybe even text or a video to Summit and have the app temporarily store it. Then when you compose a comment/post have a way to add the temporary files to the comment/post.
