No, they weren't. You uploaded thumbnails; not the actual images. Look at my profile image, for instance. As a thumbnail, it's small, but the actual image is 1280x1156. If you want to upload images that aren't already on the wiki, you need to open the actual image on your browser, and not simply right-click the thumbnail and press "Save".

As for whether or not a category is useful, think of it like this:

Are there multiple images pertaining to an article? If not, then a gallery isn't needed. If yes, a gallery may be needed.

Of those images, are any of them extremely similar to one another? If yes, then they should be deleted. If not, then a gallery is probably needed.
