The other day there was discussion amongst individuals and the members of 
If anyone reading this participated in the discussions then you will note that there are a lot of individual opinions on the subject of citing sources for photos. As a group,
After careful consideration we decided that a post pointing out the reasons why it is useful to the community for contributors to consider citing sources for photos, graphics, and content even when they may be licensed under Creative Commons 0 or Public Domain would be appropriate and hopefully promote some tolerance and prevent strife within the community.
As a platform that encourages posting creative content, it is easy to assume that when you read a post or see a photo that the curator posting that content is the “owner” of that content. It’s also easy to assume the opposite is true in the context of steemit.com being a social media platform.
The truth lies somewhere in the middle. Not everything curators find here will be “original”, yet contributors will voice interesting insights, beautiful photos, original graphics, or even interesting photoshopped images.
So the question is how do we as a community recognize the parts of an author's post that is the contributor's original work and the parts that are taken from other sources? I think the easiest thing to do is to cite all your sources. This doesn’t have to be a long tedious process of posting links under each individual image or quote, although we would encourage users to do this as it is more professional and may lead to better rewards from curators.
For those wishing to simply cite a list of sources used, at the bottom of the page include a section labeled “Sources:” and paste links as you write your post as we have done in this post and in the image provided below:
If you are more meticulous, you can also follow the example 
Do use the Markdown to denote quotes such as the one here where 
it is a gray area that users are going to need to be tolerant on. Personally, when I'm browsing, as long as the source is cited and it isn't tagged #photography then I give it a pass.

As a group we strongly encourage each individual to evaluate the given “evidence” before taking the action to upvote, flag, or comment on a post. Our hope is that as individuals and as a group we can do our part to help steemit grow into an unique platform that is successful for everyone that contributes with their creative works, thoughts, and opinions.
