Just a note...
Google.com is a search tool/engine, so it can't be the actual source (although maybe you found something by using it).
In other words, your source links should be linked to the actual site where from you used something (photo or whatever and if it was allowed to be used for free and for commercial purposes).
(Posting on Steemit is considered as commercial usage as we are earning real money with it.)
Otherwise, no-source, inappropriate sourcing or an unauthorized usage might be considered as plagiarism or some other kind of abuse, and I'm sure you don't want to be penalized for something like that.
Therefore, post wisely by taking care of copyrights and Steem on!
