Are you sure you didn’t meant to post those sequences in Awesome sequences? beautiful photos you made there.
Short answer to your question: You can’t.
Long anwser:
Atm there are some problems with the way change sets are handled, so you can’t put more than 100 changes in one change set.
You can ask to hide the whole sequence via the edit page and then re-upload, but that won’t work with change sets bigger than 100 photos. The good news however is that they are reworking the way change sets are handled. So you may have to wait for that or maybe one of the devs has a better solution.
