We want to run a contest with a very important client's account (~ 5M followers), and they have cool pictures and videos on their gallery, so we don't want our contest to change that.
The contest is pretty straightforward: When you're getting close to the prize (say, tweet #10000), we send an autoreply to the users with an image that they're getting close to the prize. The image is from a list of predefined images (5 items), same for all the replies.
Of course, we first upload the media and get the media_id of the images. Then we repeatedly use those media_id(s) to reply the tweets that are getting closer to the prize. Albeit is the same media_id(s) we use on every reply, the gallery is repeating the image of every reply on the gallery.
So, is there a way this not to happen? Maybe the image appearing one time only, or not appearing at all at the gallery?
