It should at least be an option to use the original photo! I thought perhaps if you attached a photo instead of snapping one you'd get the whole thing, but sadly that doesn't seem to be the case.

For what it's worth, photos attached from the Mac do not have this destructive act performed on them, so instead of attaching the photo to an action, just make an action reminding you to retrieve the full-resolution photo from the iPhone when you are at the Mac. Much less convenient than just attaching the photo, but you could collect a lot of unreadable photo attachments in the time you'll likely wait for Omni to update this. It's particularly unfortunate that if you just take the photo from within OmniFocus, the original photo is apparently not stored in the Camera Roll, giving you no opportunity to recover from this!
