And by credit, that includes this:

It’s link back to the original source, contains link to the certain entry AND link to the artist’s page (if the art is from pixiv).
Sorry for being annoying about this. I have at least two reasons.
1. Artists sometimes delete their works so I want there’s link to their page as well in case that happens. I want you to know who created the nice/wonderful/awesome/etc art you like.
2. There’s a probability that the artist will find their artwork posted to other site. They may think that someone stole their arts since some Japanese artists can’t understand English too well. You don’t want they stop drawing/posting their arts, do you? (Well at least I don’t!)
If they see there’s familiar phrase (title + artist name) on the post, they will think that the site just promotes their work or something. (At least I hope so. Well at least I’m trying to make it look like that.)
But you may delete my comment on the post:

I write my comments in smaller font. It’s usually light translation or just silly comment. It’s not important.
Just don’t remove the credit line. That’s what I only want from you (-ω-。)
Thanks for reading.
