@ethandsmith - When I first started using public domain images (photos as well as clipart), I had a hard time getting my head around all the different license usage terms. A few days ago I wanted to use an absolute "yummy-looking" pic on one of my posts and although the site provided a full commercial license without attribution type URL, I had no clue how to use/code it here on Steemit, so I searched for another image to use.
I am glad that you decided to do these in-depth and detailed posts for newbies, I know that people will benefit from it . Off now to read your post about voting which I also do not really understand a lot about at the moment.
Looking forward to many more of your informative posts.
