Sort thumbnails

To support sorting of thumbnails, e.g. by name, we would need to reduce the possibility of having only a subset of thumbnails loaded (via pagination), probably by increasing the page size to e.g. 500 or higher, but lazy loading the thumbnail images themselves (so as not to load a large number initially).
If some images weren't loaded, disable sorting controls, or allow with a warning?
