Not sure about the use for this, but here is a tool, “Full Page Screen Capture”. Pretty much self-explanatory. It turns a web page into a jpeg. Click on the link below to enlarge it. Works pretty fast.
Not sure how to use it. I snarked out a bit using Snag-It
Does not work for behind paywalls. Sighs all ’round. My wife, a busy knitter, says it might be very useful for free knitting patterns online. She says a picture is perfect for her uses. Let me know if you find any other uses.
