Insert image from camera


I can use OmniOutliner on the Mac to take an image with my iPhone or iPad and insert directly into a field. and if I do so, it shows up in the document on the iPad in OO. But I cannot find a way to take a picture with the iPad camera while using the app on the iPad and have it show up. Am I missing something? There’s an option to use the iPad camera as a text scanner which is really cool, but what about just capturing an image?
