Display sizes above maximum set in gallery can be downloaded by just changing the URL
I discovered a major bug with the new display sizes. This is separate from the bug where smug mug randomly changed many of my galleries from X3 max to "all but original". But if a gallery is set to allow a max of X3 for example, you can still download larger sizes by just changing the URL. This used to not be possible before. For example on this image:
I can click the sharing button and get link to the image:
If OI then copy and paste into a browser window I can just change the X3 to 4K for example and I will actually get a 3072 × 3840 image. This should NOT be possible! It doesn't matter whether I am logged on or what browser. It always works.
