I think you may have made this post a collection by mistake. Sadly this can't be reverted and you will likely not get much views or interest because you selected collection when it is clearly a post and will be displayed as an empty collection.
Collections or "Curated Content Collections" have a curator/author that collects different Hive posts into one place.
As a side note you have added a bunch of pictures without the source to these pictures if you do not have permission to the images (such as pictures that come from feed use) or own them yourself then that is problematic not just for Hive but for publishing in general.
We hope that these tips help inform you... we know you're new to Hive/Peakd and maybe publishing in general we hope that you continue, learn and progress
