A couple days ago, DrPepperfan (I think) asked me how I'm able to find image sources so quickly.
How, you ask? To be honest, DPF, usually with absurd ease. To quote one of my past posts, "search engines are credit to team!"
Another part of it, though, probably comes from my years of experience with art websites like deviantArt and FurAffinity. This part I will now share, for the convenience of all persons who wish to find image sources, the original artist(s), and/or other pictures by the same artist(s). (This info applies mainly to meme-related artwork, especially those images posted on the My Little Pony: Friendship is Magic and Furries pages.)
STEP 1: CHECK FILENAME
Each art website (deviantArt, FurAffinity, etc.) and general image posting site (Ponibooru, E621, etc.) has its own file naming scheme. If you're lucky, the posted image will retain its original filename, making the original source (mostly) easy to find.
Filename: [title of art piece; all non-alphanumeric chars replaced with underscores]_by_[artist name, same deal with the underscores]-d[base-36 code].[jpg/gif/png/whatever]
Art page: http://[artist name].deviantart.com/art/[title of art piece, with hyphens instead of underscores]-[the base-36 code converted to base-10] OR http://[artist name].deviantart.com/gallery/#/d[base-36 code]
Filename: [10-digit number, usually starts with 1].[artist name]_[misc. words relating to pic].[jpg/gif/png/whatever]
Art page: http://www.furaffinity.net/["full" or "view"]/[upload number]
Example: "Young Rainbow Dash" by AtomicGreymon on deviantArt
Example: "-Kihu commission-" by AJ-TheCanaanFox on FurAffinity
