If you go to an image page, ex. http://gravityfalls.wikia.com/wiki/File:S1e18_Staircase_entryway.png at the bottom it says "Categories:" You have to add the category for the image. In this example it's "s1e18 images". You haven't added categories to any of the images you've uploaded.

And yes, it's totally fine to upload jpgs as long at they're high quality. It's just easier for most users to replace if need be with pngs.
