@Trougnouf: , what's the difference with the JPG version? Henxter (talk) 15:18, 11 March 2021 (UTC)

@Henxter: It's practically the same image, with the dimensions reduced to multiples of 64 to make it easier for some applications like image compression. I made Category:Commons Test Photographs to have a common set of test images to assess the performance of different compression algorithms, without overlaping with Commons:Featured pictures which I use to train compression neural networks. It's better to use the jpg version on any Wikipedia article or web page since the filesize is much smaller. --Trougnouf (talk) 16:56, 11 March 2021 (UTC)
