I came upon this thread and thought I'd add.
One fast easy way to have a security in your posting of pictures is;
crop them just a tad and if you ever see it someplace, illegally, only you will have that missing corner or two thus, one way of proving it is yours. There is information embedded in most digital cameras that can prove it was the same camera you own.
Your extra corner (that you cropped out before posing and in an *Original Folder* backed up *lol) will help you prove it was taken from it (your camera )
Another is watermark, there are several programs that can put a watermark, and some are not visible to the naked eye.
About your opinions, knowledge, experience, how to word form communications,
that you freely give.
Write them first in a word doc with date and time in bedded in them, and save in named folder .
Make a folder or ten *lol with just the info you posted and where, I speak of valued information not Happy Birthday *lol
I mean concepts that are informational how to, I did, I found that... although you own all you write, doesn’t hurt to save first. Also, no need to put everything you write into a that folder unless of course you want to. We sometimes underestimate just how valuable the words we write are because we get pleasure out of sharing, keep this in mind. We all have something in our writings that are of value. Posting is one way to prove the date if you haven't saved it in a folder.
Hope this helped you feel more comfortable in posting away!
US Copywrite Laws are strict and faithful in being upheld, protecting our ownership.
As far as my knowledge, with pictures and writings they do not fall short.
Happy Posting and Sharing My Friends!
Now, Hand drawings/painting of any kind...aren't as conclusive.
Someone can add a fence to your scenery and call it theirs,it is a challenge.
