Lead image
Finally, you have an ability to select an image that will be displayed on the main and topic pages. Actually you even have to select one now. Luckily it's pretty easy with Unsplash integration - just search for some nice image and be done with it.
Yeah, it's called "lead image", because someday we'll give you the ability to have a nice big header image as a background or something like that. But for now it's used only as a thumbnail for the main/topic pages.
You can also select one of the images in your article as the "lead image".
This should definitely improve the situation with the big number of black and white images on the main page.
UPDATE: It seems to be working well, homepage looks much better now:
I was eager for this feature, thank you!
