Well, let's take this one, since it's the easiest.
 * The source is always where the image originally appeared. In this case, it's from Revenge of the Sith.  So you'd cite Star Wars Episode III: Revenge of the Sith as the source, with a bluelink to the Wookieepedia page.
 * Claiming fair use is all well and good (admins don't advise one way or another about whether it actually is Fair Use as U.S. copyright law defines that term; you have to figure that out for yourself), but for this (and any other screenshot) there's actually a more specific variant (imaginatively named "Screenshot").

Since you asked for help (which a disheartening number of people don't), I'll actually go one further and tackle a harder one to help you. Take this one—not from one of the films, obviously. Although I happened to know whence that image came, here's the step-by-step process I used to verify:
 * 1) Go to the image (here).
 * 2) Right click the image, then select "View Image".
 * 3) On the resulting image-only page, copy the URL.
 * 4) Go to Google.
 * 5) Click "Images" in the upper right.
 * 6) In the resulting search bar, click the camera icon (when you mouse over it, it says "Search by image").
 * 7) In the new box that says "Paste image URL"...paste the image URL. Then hit Enter or the blue "Search by image" box.
 * 8) Here's the key. On the search results screen, look for a result on Wookieepedia; Wookieepedia, like SWFanon, requires sourced images.  Here, the very first result is, so click that.
 * 9) Conveniently, you don't even half to comb the article for the image; in this case, it's the infobox image. Left click, and then, when you have the blown-up version, click the image title (here, "Lord Khan EGF.jpg").
 * 10) That takes you here, to Wookieepedia's equivalent of our image pages. Scrolling down, you can see that the image comes from , and that the author is.
 * 11) As a result, you now have both your source and your author!

Reverse Google Image Search like that is a very useful tool for tracking down image sources. Any time the image appears on Wookieepedia, you can probably find all the sourcing information you need there. Reverse Google Image Search is also handy for finding original sources and artists for works on DeviantArt and ArtStation.

That should get you a long way toward tracking your sources down. If you need more help, let me know.
