Please note that a great deal of discussion regarding featured pictures, including all discussions about individual featured pictures, takes place at the FP candidate page.

If that's a issue, I could crop this image (I'll remove the rest of the frame). This file is a cropped and lighter version of the TIFF file File:Jan Matejko, Stańczyk - hi-res tiff.tif, coming directly from the National Museum in Warsaw, where Stańczyk is exhibited. I believe this is the best photo of this painting available - as you pointed out, it shows more details than this one from the Google Art Project. Gytha (talk) 11:11, 16 January 2023 (UTC)[reply]
File:Jan Matejko, Stańczyk.jpg is better (higher resolution and more detail). @Gytha: the left edge needs a crop (maybe 15 pixels or so). If you do that then we can do a "delist and replace" nom (I will do the nom if others don't do it first). The current FP at this link is no longer used in any articles, so we should replace it in a "delist and replace" nom. Cheers. Bammesk (talk) 03:10, 17 January 2023 (UTC)[reply]
I was just looking closely at the article and featured picture of Marie Stopes(right). The thumbnail on the main page doesn't seem to work as well as it might because it's a wide shot with a lot of murky background and the detail of the central subject is hard to make out at that scale. For example, I didn't realise until I clicked through and zoomed in that she was using a microscope. So, I was wondering whether there's a technical option for the thumbnail to show a cropped version? Andrew🐉(talk) 10:56, 9 March 2023 (UTC)[reply]
I reckon the FP section would be better in the top right slot on the main page where it would form a natural pairing with the Featured Article. As this would require some restructuring of the main page I have started some discussion at Talk: Main Page. Andrew🐉(talk) 10:19, 10 August 2023 (UTC)[reply]
