@paperdigits, I think there is a website/browser issue. My post above starting “I’m using image viewer” has the same jpeg twice. I assumed I’d messed up. So I just tried to correct it. So I deleted the second jpeg and uploaded the correct one. Whist it’s uploading, all looks okay, it’s the file name I expect. But when it gets to 100%, the file name changes to the same as the previous one, i.e. indigo-bunting-test-sRGB-abs-col !!! I did this twice, once dragging/dropping, and once using the upload button. aaaagh!
