I'm sure it's the way to go and over time more people will vote for you and leave comments! In Hive, as in so many other places, it is important to persevere.
Regarding the images, if they are yours, it is enough to say that they are, and if they are from others who offer them with licenses that allow commercial uses, then you have to cite the source. If they don't have a free license, then you can't use them. If you want to see some examples, you can visit some of my posts.
By the way, my name is not PIZZA. When someone puts in a comment things like !PIZZA or !LUV it means that they are giving you a tip on that token, which will appear in your Hive-Engine wallet. This cannot be done with all tokens, only with tip tokens.
Cheers!
