Thank you for reading my post and your upvote!
Not a problem for me at all to give a credit ;D
To be honest many people are using my own photos and I always feel being proud of myself when they do it, regardless of any credits. Surely, I might be wrong about it.
Also, in trending section I always see lots of posts without any credits, but nevermind.

I don't bother with trending posts because I can't get them to bother with citing sources. I fight the battles I can win and hopefully those that do the right thing will eventually dominate trending.
