Hello Hive account@owenmaya,

A disclaimer had earlier been made in this post to use these images for few hours before we drop it.
Author should make a disclaimer at the entrance into the contest.
Be aware this is contest, and as such, entering into the contest does not guarantee your winning. Moreso, uploading any image of your work automatically and impliedly award the organiser full right to make use of the images in ways he deem fit, otherwise, you won't have to participate or rather make a clause restraining the organiser from using such image if you lose in the contest, perhaps that isn't a good practice.

We hope that you reconsider what the right etiquette connotes.
