From what I can see, it is still pretty rare to release downloadable images at a decent resolution, so it is excellent that Getty is getting good press for this. For example, the National Gallery has high-resolution scans, but they aren't downloadable (perhaps you can scrape them, but that isn't accessible to most people). LACMA has only low-resolution images. Off the rest of your list, Rijksmuseum and the Brooklyn Museum have only low-resolution images, Cooper-Hewitt and Europeana have almost nothing (only very low-resolution). I haven't checked everything. Maybe you are right that it is becoming more common, but I can't see that myself. The Met is the only example I know of that compares. The Met does have decent resolution downloads available, but the Getty's downloadable scans are still much better.
