I would like to submit Picross speedruns, how do I do it?

I used to play Minesweeper a lot back in the day (my mid 20s) when I was only working part time. I'm 36 now. I have two saved screenshots of my two best times for Expert. This was all the way back in 2011 (almost a decade exactly from the date of this post). There was no streaming or capture back then obviously, but I was proud of it so this was all I had. Can I submit these screenshots of my old ass times? They aren't anywhere near the top times, but they would be my first official speedrun.com submissions and would put me tied at 50th and 65th respectively and I only just got into watching speedrunning in the past year or so.
