Problem with Gallery in Activity AND mobile phones

Hi Kyle, how can I identify a post that has a photo attached that was uploaded on CB gallery? Here is the reasoning: We have built an auto-action that sends a push notification each time someone comments on a post. We can already identify who is doing the comments etc... but we would need to also be able to identify if someone has uploaded photos to CB activity (so that we can send a message with "XYZ has just uploaded photos on your event/wall/stream"
How can we do that? Been searching in db but havent found anything...

If it's from CB Gallery the asset will be "gallery.TYPE.ID" and you can identify it that way. If you mean photos directly uploaded with a post then best you can do is probably to check if [VAR_params_gallery] is empty or not. If it's not empty then some sort of media was uploaded with the post. As for what var to use it depends on what trigger you're using, but you'll need access to the activity object.
