Posting pictures in groups is great, but rather than writing a message and attaching a picture to said message, a dialogue box opens for the message you want to have with it, which is great and all, but limits the amount of characters. So, either continue the message in another post in the group, or post the picture then write the message (or vice versa). Either way it is two notifications for the group. Doesn't seem like a big deal, but when you are trying to limit the amount of notifications your clients get so they don't disengage, its noticable.
