to capture a pic, use the print screen key & then some app, I use paint, and crop out the part you want to keep, open a new page & past in the kept part & name it, then use a pic hosting site (since it appears we cannot upload here) like flickr or photobucket & link to it here.
Also, here is an automatic karuko solver - you have to follow the instructions to set the board
