v3 adds a new config file (old .txts will not work), adds support for multiple screens, allows you to remove files after upload and allows external uploader support.
v3.0.1 fixes a bug with external uploaders where it didn't copy the link and:
THIS VERSION PACKS EXTERNAL UPLOADERS. If you want to use your own server, download ftp.zip. If you want to use a free service, go with imgur.zip, quadfile,zip or imagebin.zip
READ THE LINKS ABOVE. They are important for setting it up.
v3.0.2 fixes a bug where window or fullscreen capture wouldn't remove the file (#11)
v3.0.3 fixes a bug where partial capture wouldn't be able to reach fullscreen image and crash (#12)
