When you post something that is not yours, you need to cite your source. If you didn’t write it cite your source.
If the picture you post is not yours cite your source
If you used a recipe you found on another blog but made “a few tweaks to make it yours” which in reality you used someone else’s recipe and decided to do half a cup of brown sugar instead of raw sugar that is not a new recipe and not only should you cite your source you should NOT share the recipe on your page. instead link to the original post and talk about your tweaks.
When you post on Facebook, cite your source.
When you post photos that are not your and claim that they and the crafts are yours or at least don’t say they are not so anyone readying would assume they are. That is called stealing.
Don’t steal your better than that. Cite your sources, give credit and links where due.
