Previously, it was possible to upload pictures to Habrahabr only in JPG format (as proof, I offer a
comment dated yesterday). But today, when I wanted to write a new post about the imminent release of the
next version of the debility Netscape 9
browser , I found support for PNG and GIF. So, without too much pathos, Habrahabr programmers added support for new (sometimes very necessary) formats!
PS: About Netscape write to change my mind, who needs - see
here ;)
