I don't really want to impose my newfound and astonishingly-accurate method of accrediting authors to the their works, but really simplest way to explain it is by my embracement of two key web applications:
tumblr and
TinEye. On the ohter hand, if I see an image without any description whatsoever, I get kind of pissed (better fit word: "fueled") and try to see if I can find the origins of the image, within 2 minutes is a bonus.
I've known about both websites for more than a year now, perhaps verging on two, but only in the past six months have I joined the two forces together to find the source and creative intrigue that inspired the creation that I am now beholding. Not enough people state their sources, anywhere really, but of the hundreds of blogs I've come to uncover over the past year, and along with some of the people that I follow on tumblr, flickr, 2photo, deviantart, and dozens of other locales, I can at least rummage around myself and see if I can put the right name to the right picture. It's my goal; and it does help me uncover other great astounding works by the same author, and/or their peers.
If you see how I've adopted the "bracket system", that states where I found the source;
for example:
you say you found this image
here, but couldn't find the author. I'd post the image...and just bracket the source

But if I did happen to find the creator, I'd state right under the image, post its "title", and give a link to the author's webpage, if he/she has one, along with their name.
