quick tip for anyone with a bloated screenshots folder who wants to reduce its filesize:
>install ImageMagick
https://imagemagick.org/script/download.php#windows
>open your VRC pictures folder, click the address bar and type "cmd" to launch command prompt in the folder
>type "magick mogrify -format jpg *.png" without quotes into the cmd
this will convert all png's in the folder into jpg's with little to no quality loss while still keeping the original file in case a conversion didn't come out like you wanted (I haven't had that happen to me despite converting thousands of images)
