Upload a small image, only a few lines tall.
With all the “Caption with AI” banners etc. it is hard to see your image in the preview window.
What’s worse is the confusing 100% 75% 50% dialog (with no mouseovers on each button.)
At first glance it seems like a upload progress indicator.
Good, my photo uploaded 100%.
But now come to think of it, they probably are for if you want to resize your image to that percent size. Ah, no wonder the 100% is not clickable (thus black). Again, mouseovers wouldn’t hurt.
