I got tired of thumbnails that are just zoomed in on someone's face, so I made a small .exe program to generate thumbnails.

Click on "weasyl_thumb.exe" then "view raw" to download it.

You can make a shortcut to weasyl_thumb.exe somewhere, drag an image file (png, jpg, etc.) onto it, and it will make a file "thumb[filename].png" that's a 240x240 square. Use this as your thumbnail on Weasyl!!
