Also wondering if there are any thumbnails that are larger than their actual images, and if yes to get rid of them.
For raster image formats, we don't generate thumbs larger than the original -- we just use the original image and let the browser stretch it to the requested size.
For vector image formats (SVG, possibly PDF) we can and do generate thumbnails larger than the canonical width and height, so that tiny SVG files can be scaled up. But a hard limit is enforced, I think 2048px or something.
