If you play in Facebook there's a little camera icon that puts a pic in your feed that you can save and upload here. I don't use that, I take a screen shot (shift key + Prt Screen) and then open Paint (or any image program) paste it in (Control-V or use menu) select and crop as desired, save.. (I also keep an archive of records of my team on my hard drive) then upload here. Many people use photo hosting sites to paste in the image code, so they have the large picture.
