Not indicating that the content you posted including images is not your original work could be seen as plagiarism.
Please refrain from using #photography for posting art, graphics, memes, or other people's photos. Repeated use of the #photography tag when posting other people's photos without attribution or indicating it isn't yours could also be considered spam. Spam is discouraged by the community and may result in action from the cheetah bot.
If you are the photographer please reply and let us know!
I have used photography hashtag because the article is on photography topic. I have already mentioned that "All Image Credit: Creative Commons", please read the footer. These images are Pixabay images, all creative commons.

On the Steem platform you still need to provide a reference. This is because content is monetized. Also, you've used the #photography tag. Using that tag indicates that you are implying that you are the photographer. Although the post is about photography, the implication is there and is specific to the Steem community.
Going forward, always add reference links, even if the images are Creative Commons and use the #photography tag for photos taken by you.
I wish you would have told me this before you downvoted me. I lost so much of money. Being discouraged, I have completely stopped using images and photography tags in my posts.
